Okay, I think I finally got it working.
Sorry for the mess but using the highlighted elements in setup makes it so that the box trace is one-way only, thus preventing my player character from being able to damage enemies by jumping through them. You can get a more in-depth breakdown [here][2] starting from the eleventh post.
along with [L1z4rD89][3]'s box trace fix appears to have fixed all of my problems.
Thanks for all the help!
