Can I delete an old form name from the filter?

Hello all,

There doesn't seem to be a way to delete old form names from the filter in the contacts area. Does anyone know if this is possible?

When I saved a section that had a form on it, and added that saved section to a new page the form name plus a 2 was added to the form names in the filter.  It didn't change when I edited the form name. And I can't delete it. This may not seem like a big isue but fo the purpose I need to use the filter it is quit annoying. 

This form is behind a paywall for a course. 

here is a screen shot. the form name Wshop 2 - Topic 2 2 needs to be removed.  Any ideas? thanks.

Still no feedback on this one?
