Renaming Groups

I encountered an odd problem after more or less completing a map model for my D&D game. for the floor tiles i use several Plate 4x4 (3031.dat) in slightly alternating colors.
The problem is that when i try to rename a group to something more appropriate for D&D like Kitchen or Garden, by right-click-> Properties, the group disappears from the model. i can only bring it back via the undo button.

Is this a bug or a feature, and if either, what can i do about it?

It's not a feature

But I can't seem to replicate this.

Did you do anything else 'special' before or after changing the name?

just tried it again and something seems to have been fixed. but now i'm missing a few parts from my favorites list, u9504.dat for one....
on my first big model the problem . except now in also moves the selected group, where before it was located at x1,240 y0 z3,400 it changed the , to a .
maybe update to not use a comma in numerical values?
edit: deleting the comma when renaming the group retains original position!
