Hi, Im a student trying to learn Solidworks, and Ive gotten quite far in my model, much too far to turn back now, and suddenly solid bodies that were used in an combine (subtract) a while back are reappearing when I go back and edit certain features...The feature im trying to edit has nothing to do with the previous combine, but its reappearing on top of something im trying to edit and its making it to where I cant see the part i'm trying to work on, any suggestions?

EDIT: I was messing around with different things, and when I deleted my combined feature it fixed the problem, which causes a new problem, I need that combine to move forward...When I re-combined the parts, it caused the same problem. The combined parts are completely unrelated to the part that I am attempting to edit. It seems to make the "hidden" part appear no matter which feature I try to edit on the entire model.
