Shadow/Halo problem? My CC looks like it's floating.

How do I remove the halo/glow that appears around an item that makes it look like it's floating in game? It happens in some cc but not all, so I can't figure out how to fix it. I've followed the tutorials listed here and searched but found no answers yet. Thanks in advance!
