I HAVE ASSIGNED ALL ASSEMBLY COMPONENTS A COMPONENT REFERENCE NUMBER.  i HAVE ALSO CREATED A BOM WITH THE COMPONENT REFERENCE NUMBERS (WORKS GREAT), BUT FOR SOME REASON THE BALLOONS DO NOT SHOW WITH THE NUMBER WHEN THE COMPONENT REFERENCE IS SELECTED AT THE TIME THE BALLOON IS BEING CREATED.  ACTUALLY THEY ARE BLANK OR HAVE THAT ENVELOP SYMBOL IN IT.  PLEASE HELP.....WHAT AM I DOING WRONG?
