Front Derailleur Help - Chorus 11 on Ritchey Logic Cranks

Hoping someone might know a trick to help me get Campy Chorus 11 FD shift properly as I’m at my wits end and have tried every way possible with no luck.

I’m using a Ritchey Logic Compact triple as a double with TA 9 speed 50/34 chainrings with a Chorus 11 2015+ group (copied this exact setup from Pat from Ultradynamico’s Romanceur). Shimano 11 speed cassette and chain, everything pretty much new. Kind of a mix and match group so I’m sure that’s not helping but I’ve seen it done!

When I go to shift up into the big ring the chain moves up to the upper ring but doesn’t quite make its way on to teeth, it will just continue to ride pinched against the side of the FD cage and the teeth. In order to get it to shift all the way up I have to over compensate and add extra tension, plus the outer limit has to be moved out enough to allow the inside of the cage enough movement to shove the chain that last mm or two over to make it onto the teeth - at this point the chain is very prone to over shifting and dropping or the FD cage itself actually runs into the crank arm! This also requires me to throw the lever all the way twice and not in a single shift.

I have tried raising and lowering the FD tons, angling the cage in or out a bit, and adding tons of extra tension to no avail. I’ve set up plenty of FDs in this past and never had this much trouble. Any ideas??

Thoughts:
-is it just impossible with my crankset setup?
-is there a way to adjust the leverage or throw of the FD arm? I’ve got the cable correctly routed around the top of the tab
-I do remember thinking it was weird but when installing my cable the barrel at the end didn’t drop into or recess into the plastic ratchet mechanism inside the shifter body, but instead just sat on top. I tried and poked around to see but it really didn’t seem like there was a recess it could drop into. Could that be an issue?
