Frame removal in Astrosurface or AS3 please

[fwm891]

Hi New to planetary processing and I've hit a snag. Some of my frame captures show only a partial frame with blank area usually bottom of the frame (see screen grabs).

So when I load the file(s) and analyse it puts all these frames at the 'Best' end (which is good) but I can't see how to delete them so I can select the frames I want?

Anyone know how to please.
