[SalesForce] Access Check Failed! even though component is marked with access of global

I am getting the following warning in the console even though my component is marked as access="global". This makes no sense to me. Is it possibly an issue with the debugger?

These are the warnings I get in the console whenever I click the checkbox.

WARNING: Access Check Failed! Component.getEvent():'click' of
component 'markup://ui:inputCheckbox {22:37;a}' is not visible to ….

WARNING: Access Check Failed! AttributeSet.get(): attribute
'disableDoubleClicks' of component 'markup://ui:inputCheckbox
{22:37;a}' …..

aura_proddebug.js:14495 WARNING: Access Check Failed!
Component.getEvent():'change' of component 'markup://ui:inputCheckbox
{22:37;a}'…

and this is the component code:

<aura:component access="global" implements="force:appHostable,flexipage:availableForAllPageTypes" controller="ListRacesController">
<aura:attribute name="races" type="Race__c[]"  />

<aura:handler name="init" value="{!this}" action="{!c.doInit}" />
<!-- key here is that the handler has no name attribute specified when dealing with application event -->
<aura:handler event="c:addToRaceList" action="{!c.handleAddToRaces}" />
