Hey all, just bought a Colnago CLX 3.0 2012 with Shimano Ultegra Di2 RD-6770. After removing and reattaching the rear wheel for transport, I noticed the derailleur seems to be folding the chain back on itself when on both smaller sprockets. Still a learner so I'm a bit lost on what to troubleshoot first.
Should I shorten the chain, is it ok to ride if I avoid this gear specifically, should I adjust the b screw?

Definitely shorten that chain, for it to fold up, there is absolutely no tension there which the chain provides to pull it down
