Bugs
This occurs more likely when you acquire the Jury Rigging perk. When you equip a faction armor and use it to repair another armor. The faction armor disappears from your body but the game will not register you as having unequipped the armor. This means you are stuck with the particular faction until you find another piece of the same faction's armor, equip and unequip it.
