Skin Bug in Team Builder.

So there is a feature in the champion select which keeps some of the skins that you bought as default for some champs, and there are some that are unequipped for some odd reason I do not know why. Also, there comes a time where both the default and the skin that you bought are both equipped on my screen and it took me a while to find out that I had to reslect the default skin and then select the original skin I wanted to have. Riot, please remove the feature or fix it pls. It confuses me a lot.
