OK, I have recreated the problem that I have but I 'm still dont know how to fit it.

I took the archive that you send to me. It compile OK.

Next I change it back to lvds and IOBank to 2.5v, now pin planner creates the other diff signal and assigned C14 to it.

It is when this field is empty then it compile.

How did you get this field to be empty
