unable to add a note to the sheet format

Months ago I linked the sheet title to the page title on our drawing templates.  But now, on one, I cannot even add a note of any kind while editing the sheet format.  If I change the sheet format, I still cannot add a note (but I can on other drawings that use the same sheet format).

I've restarted StupidWorks twice, to no avail.  I don't understand why I can do things SOMETIMES, but not others.  The existence of inconsistent programs baffles me.

Suggestions?
