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.
