I just upgraded to Solid Works 2015 and noticed an issue with the revision block when creating a new revision.  I found that not every time, but about 50% of the time when a new revision is create the text "B1" gets added to the end of the text.  If I erase it, it just comes back.  The only thing I have found to eliminate it, is to delete the revision and the create the revision in the revision block again.

Anybody have any ideas on how to get rid of this issue?  It is mainly an inconvenience.  When I finish the drawing it looks good, but sometimes when it gets reopened the "B1" text comes back and then I have to fix it again.
