Project description:
Replaced 2 ceiling light fixtures with 4 recessed LED lights on 3-way circuit. Also replaced (2) 3-way switches, one with dimmer and one standard, and (1) standard 2-way switch feeding outside porch light.
Problem:
Can't get both 3-way switches to operate the 4 new recessed lights independently. Currently, in order for the 3-way dimmer switch (on right) to turn lights off/on, the 3-way standard switch (on left) needs to be flipped. I feel like I've tried every possible wire combination tied to the 3-way switches but no luck. The 2-way switch controlling outside porch light worked fine with every combination I tried, and it makes sense with power from breaker connected directly to switch for porch light.
I can add more pictures or answer any questions to clarify anything. Thanks a lot for any help or advice.
OPTION – based on feedback from first post and looking back at the Lutron Diva CL 3-way switch diagrams, heres a new drawing of what seems like a solution. Really appreciate any/all feedback.

Looking at your diagram, you are using the white wire as hot to the left-hand switch and black and red as travelers between the two 3-way switches. On the left-hand switch, you will find (excluding the green ground screw) one terminal looks different, probably a different color) than the other two. This is where the white wire goes. The black and red wires go to the other two terminals. Your diagram implies that this is wired wrong as you show the black wire going to the separate side of the switch.
Two more comments: (1) I’m assuming that you also have ground wires running everywhere that you just haven’t shown. If not, stop and get a professional to help before you kill someone! (2) You should add black tape to the ends of that white wire to show that it is not a neutral wire.
