That is probably because your turntables axis are both on the 2nd motion group, declared as axis1 and axis2.
The group exchange uttility I do not remember if allows to interchange an axis for another one, I do not think so...
You may need to extract that .tp file from the controller, convert it to .ls format, then go to the point declaration part and exchange the group 2 axis manually on all points from A1 to A2. Finally convert the .ls to .tp again and load it.
That is what I have done in the past while adapting programs whith servoguns, this should work the same way.
