door headers labels not grouped for same door sizes

[SkullMesaRanch]

I'm trying to finalize my construction plans and changed an interior door size to be the same as 5 other interior doors.  Even though it's the same header size as the other doors CA gives it a different header label and places two line items in the schedule and parts list with identical dimensions.

 

I tried deleting the doors and replacing them.. and that worked.  Except when re-framing some walls, now closet and window headers have the same problem.  This has got to be something very simple but I just can't find it.   How do I make all headers of the same size have the same "T" label?

I gave up trying to keep my framing schedule format and just hit auto frame and all the headers were grouped properly.   Problem solved.
