I'm trying to delete a revision row in a part drawing title block within the Edit Sheet Format command... I can select the text, I can modify the text... but I cannot delete it.

Or anything else in the title block for that matter. I can add items... text, lines, blocks... once they're there, can't delete them.

Even if I open the original template, can't delete anything.

Is there some kind of setting somewhere?  I was just editing title blocks yesterday and was able to delete items.

SolidWorks 2014

Thanks in advance
