Purchase error on PC Client: "#ref.ALREADY.OWNED"

I have been unable to purchase the new kyrotech pack, with the code "#ref.ALREADY.OWNED" showing. It started last time the pack showed up, when i purchased it once on an Apple device, and when trying to purchase the 2nd on the PC client, it showed up for the first time. This time it doesnt even allow me to purchase it on the Client at all, w the same error. AC: 631-528-231
