MASC won't remove from Assign Crits if removed from Structure Armor Tab

[HammerGS]

If you load a unit with MASC (Gunsmith) if I change the selector on Structure/Armor to no MASC it still shows on the unallocated equipment box on the Assign Crits tab.

You can add both Clan and IS MASC and not have them removed.
