Missing Tabs of Form

Good day all.  I just created a new ItemType (Software).  I built it to resemble the Part ItemType.  Everything seems to be fine, except none of the Relationship tabs are showing when the form populates.  I've compared the SW form to the Part form & can't see anything that I missed.  I am not seeing anything in the ItemType either.  I've tried searching for an answer, but the only thing I seem to find is that there is a Hide ab button somewhere (old posts).  Thank you for the help.
