Small single walls - can't delete without deleting the body

[pixeldieb]

So i have those small walls and seem to cant get rid of them.
Selecting and deleting does not work.
Am I missing something?

This error gets in my face all the time:

"Single surfaces cant be deleted. To delete the whole body use the browser or the selection filters"

Do you have Capture Design History turned on?

Why did that face get created in the first place?
