What can I say, breaking software is a gift.  Or a curse. 

Yes, now that I realize the cause, the solution is obvious.

I renamed them because I have two OTA's, and planned to reuse the models, and the names given by APPM are not meaningful.  I put the OTA type in the name, so I could know which was which.   It's sure easier than remember the date when I last created the refractor model, or the SCT model.
