BUG: Templates are 'postpending' a number value when saving

BUG: When saving Templates after within Content Template, it “postpends” a -1 after it. Even after I remove the -1 it brings it back again: http://prntscr.com/mse7ul (screen shot is after removing, saving, back to list view, saving, and it comes back again)

** actually, after each save it adds the next number value.

At least the incremented Template Name is updated where ever it is used. So everything still works.

Start of versioning or rollback?
