InfoPath Dev

Infopath newbie here... How can I delete these signatures1 and those under it. I already deleted the objects assigned to it. I tried going to the Form Options>Digital Signature to remove the "signable data"... there are no signable data. Help! Thanks

You can't right-click on the signatures1 folder and click delete?

I can't...

Can you not do it individual for 2, 3, and 4?  I have no problem deleting them in mine.

This is what I see if I if I right click on Signature 1

And this is what I get when I right click on 2,3, or 4

 Thanks so much for trying to help.
