form field missing numeric tab

When I set up my word doc as a fillable pdf I must have checked off 'need signatures'.  Now none of the field property boxes show the 'numeric' tab.

I have read that I should be able to go to 'prepare forms' and click on 'more' on the right side of the screen but that just takes me to more tools.  I do not see an option to 'convert to normal adobe pdf'

I have already formatted the form so I hope I don't have to start from scratch.
