Recently I have had an issue start where my second hotkey removes equipped nightingale armor and no other armor. It may have something to do with I had it in the group then upgraded it. For some reason whenever I hit the hotkey for my second group it unequips the nightingale armor instead of equipping it. It is all the same as the first group I have set except for a mace. The first group equips the armor properly, the second doesn't. I have checked the settings, all unequip options are disabled.
