I figured this out by unchecking "run as administrator" for ArcMap, not really sure how it was ever enabled as I honestly don't think that I did it at any point. This also resolved another issue where I could not see any mapped network drives in ArcCatalog i.e. E:, G:, etc. -- ? unchecking run as admin on the .exe for ArcMap solved both of these issues, this was after updating to 10.6. Hopefully this helps someone else.
