I'd like to start out by saying I am new to di2 and my bike was shifting just fine on all 11 gears in the rear and the 2 in the front before I took it off the kickr to get a bike fit. Post bike fit I get home and attempt to shift the rear derailluer down to the small gear to make it easier to put on the trainer and it won't down shift past gear 8. I can shift fine inbetween gears 8-11 but nothing lower than 8. My front derailluer still shifts fine inbetween the big and small rings. Thoughts?

This issue is on a Cervelo P2 and I am experiencing the shifting issue from both the aerobars and basebar. When in the 11th gear and up shifting the RD moves inwards but the chain does not shift into the wheel, most likely due to the limit screw. This makes me think that the system is confused and thinking that the 8th gear is actually the 1st gear.

I tried going through crash test reset on di2 and it automatically upshifts from gear 8 into the wheel, this was making me think that the system thinks gear 8 is really the smallest gear in the cassette.

I downloaded E-tube 3.4.5 and it shows that my RD is in the smallest gear (11) when in reality my RD is in gear (4) of the diagram and can only shift inbetween 1-4. Sorry for using 8-11 above. 8-11 above describes 4-1 in the diagram.

I attached pictures of the RD if that helps.
