Unable to buy skin - Maximilien's Vault

Hi,

In my Maximilien’s Vault one of the options is Lifeweaver - Lifeguarder. This is displaying as Owned as I currently have it via the Game Pass skin rotation, but I don’t actually own this skin.

I’ve tried restarting, and I’ve tried equipping a different skin, but it’s still showing up as owned. Support suggested I raise a forum topic in case other people were having the same issue.

I’d attach screenshots but I can’t include links
