I am attempting to create a reducing bushing, going from a 2in sch80 to 1.25in sch80 pipe, and while I specify this in the connection points, whenever I save and close the part, and then use it in an assembly, it reverts to 2in sch40.

It seems to do this randomly, some elbows/bushings/tees are fine, and some keep reverting back to sch40.  Incredibly annoying, anyone else have this problem?
