The fact yo went to a 46T from 50T means the FDER is going to have to sit noticeably higher than normal above the big ring.
You can't lower it to match the 46T because it'll interfere against the small ring.
You may simply be having an issue because of the mismatch.
Note the gawdawful gap when I replaced the 44T with a 36T. Shifting to the big requires "help".
Any lower and it hangs against the middle ring on the downshift.
