Can't equip a Skin from my collection

Two days ago, I bought the Forged Robotics Facility form the store. However, when I click “Equip”, nothing happens. I’ve already tried restarting the client and I’m not playing any large format games either. What’s even more bizarre, when I click on “Equip Set” instead of just “Equip”, it equips the Forged Robotics Bay, which I don’t even own.
