Locked Out Of Skin Selection

I was in an ARAM today and got Miss Fortune. Now mind you, I have almost all of her skins. However, all of the skins were locked out for me. I traded with someone else and they gave me Quinn, who I have all skins for. I was still unable to select my skins. The person I traded with was also having issues prior to trading, but they managed to get their skin to work and even skin boosted - however, I was unaffected and still couldn't use a skin. Has anyone else had this issue?
