Chits returning to wrong location

I have 5 decks of chits, 3 Soviet and 2 German. The two german stacks work perfectly when returned to deck. However only the first soviet chit desk returns to the proper location. The other 2 return to the upper left corner of the main map instead!

Any ideas why?

I fixed it by renaming the deck and reassigning the return to the new names! Is there a length limit on names? Only thing I could think that might have caused it to happen. That maybe it truncated and had a duplicate name so did nothing with the chits but drop them in the corner.
