[Team Builder] Invalid_skin error after purchasing skin in champion select

After setting up for team builder, and purchasing a skin for skarner during the setup process, I received an error "Invalid_skin". I had to reopen the champion selection menu and open the skins in order to clear this error. I will attempt to recreate and get screenshots after I finish this game.

We're testing a new feature that gives the option to view discussion comments in chronological order. Some testers have pointed out situations in which they feel a linear view could be helpful, so we'd like see how you guys make use of it.
