I have a similar issue with my Shimano 5700 50-34 crankset and band-on derailleur, see telltale scratches in photo below from before I noticed and solved the problem. I don't know the provenance of my derailleur, it came second hand with the frame years ago, so I'm not sure why it should happen, but can share what I did.
Normal adjustments of the front derailleur weren't helping; with the derailleur aligned straight ahead, the outer plate would always catch the crank. If the high limit was tight enough to prevent this contact, it was too tight to allow the derailleur movement to the big ring.
So I struck a balance between high limit position and derailleur alignment. The tail of the derailleur is tucked just slightly inboard than I would normally align the FD, while the high limit is set so that the outer plate just doesn't contact the crank. I worked iteratively, angling the derailleur slightly, then checking the cable tension and the high limit vs rubbing the crank, then starting all over again if it wasn't right (patience). This was a few years ago and the derailleur operates fine in either direction, it is only skewed inboard a little bit.
Hopefully you can set up your derailleur with a little care and a little creativity to try something similar. Remember to have the rear derailleur set up correctly (limits included) before working on the front. Yours would be slightly more involved than mine because you have the newer design with the support screw and is a braze on. Then again, using the support screw to your advantage might allow you to be pretty precise in your adjustments.
No cables on the bike at the mo unfortunately, but you might see how the alignment is just slightly skewed in this photo - it is subtle!
