[SalesForce] saveRecord Component: Set Required Picklist values

I am trying to just get a simple record saved, and I continue to get errors saying I am not setting a required field, campus__c.

I have a ui:select component which should explicitly define the values. I then have that saved to both label and value? Then in my component, I try to set the value in the specific field in the lightning Record data with
component.set("v.simpleInvention.Campus__c", component.find('campusSelect').get("v.label"));
I have tried both v.label and v.value.

Here is my code:

<aura:component controller="inventionAura"
            implements="flexipage:availableForRecordHome,force:hasRecordId,lightning:actionOverride" 
            access="global" >

<aura:attribute name="newInvention" type="Object" />
<aura:attribute name="simpleInvention" type="Object" />
<aura:attribute name="accountError" type="String" />    
<force:recordData aura:id="inventionRecordCreator"
                  layoutType="FULL"
                  targetRecord="{!v.newInvention}"
                  targetFields="{!v.simpleInvention}"
                  targetError="{!v.newInventionError}"
                  />


<aura:attribute name="options" type="String[]" description="options" />

<aura:handler name="init" value="{!this}" action="{!c.doInit}" />

<div class="Create Invention">
    <lightning:card iconName="action:new" title="Create Invention">
        <div class="slds-p-horizontal--small">

                    <input type="text" id="inventionName" class="slds-input" placeholder="New Invention" value="{!v.simpleInvention.Name}"/>

Controller:

({
doInit : function(component, event, helper) {

    //Prepare new record from template

    component.find("inventionRecordCreator").getNewRecord(
    "Invention__c", // sObject Type (entityAPIName)
        "3D0121D0000000ZbTQAU", //recordTypeID
        false, //skip cache?
        $A.getCallback(function() {
            var rec = component.get("v.newInvention");
            var error = component.get("v.newInventionError");
            if(error || (rec === null)) {
                console.log("Error initializing record template: " + error);
            }else{
                console.log("Record template initialized: " + rec.sobjectType);
            }
        })
    );
}, //don't forget the comma if you have more stuff

handleSaveInvention: function(component, event, helper) {
    if(helper.validateInventionForm(component)) {

        component.set("v.simpleInvention.Name", '');
        //component.set("v.simpleInvention.Title", component.find('inventionTitle').get("v.value"))
        component.set("v.simpleInvention.Campus__c", component.find('campusSelect').get("v.label"));           
        component.find("inventionRecordCreator").saveRecord(function(saveResult) {
            if (saveResult.state === "SUCCESS" || saveResult.state === "DRAFT") {
                //record is saved successfully
                var resultsToast = $A.get("e.force:showToast");
                resultsToast.setParams({
                    "title": "Saved",
                    "message": "The record was saved."
                });
                resultsToast.fire();
            } else if(saveResult.state === "INCOMPLETE") {
                //handle incomplete state
                console.log("User is offline, device doesn't support drafts.")
            } else if(saveResult.state === "ERROR") {
                //handle the error state
                console.log('Problem saving contact, error: ' + JSON.stringify(saveResult.error));
            } else {
                console.log('Unknown problem, state: ' + saveResult.state + ', error: ' + JSON.stringify(saveResult.error));
            }                
        });
    }
}

})

As an aside, I also tried to get the values dynamically from the set picklist on the object. I tried this code:

<div class="slds-form-element">
                <label class="slds-form-element__label" for="InventionCampus">Invention Location</label>
                <div class="slds-form-element__control">
                    <ui:inputSelect label="Campus" class="dynamic" aura:id="InventionCampus" value="{!v.simpleInvention.Campus__c}" required="true"/>
                </div>
            </div>

With the controller:

//Pull campus picklist values
    var action = component.get("c.getCampusValues");
    var inputsel = component.find("InventionCampus");
    var campus=[]; 

    //system.debug("Show what vars were received: action=" action + ", inputsel=" + inputsel + ", campus=" + campus);

    action.setCallback(this, function(a) {
        for(var i=0;i< a.getReturnValue().length;i++){
            campus.push({"class": "optionClass", label:a.getReturnValue()[i], value:a.getReturnValue()[i]});
        }
        inputsel.set("v.options", campus);
    });

    $A.enqueueAction(action);
