Champion Card Stack 7+/ Regions 2+ Bug [GAMEPLAY][LOR]

During PvP [Challenge] Match with my friend we encountered this Champion Card Stack bug.

My deck ( on the left side ), Only contained Darius, Katarina, and Garen, but the Visual Cards showed Extra Champions that I don't currently own/have in the deck. Some of them such as Teemo and Himerdinger are outside the specified regions selected.

This Visual Bug Doesn't affect the game play but Here is the Deck I used: CEAAEBYBAMCAODITEY3TQBYBAABQSCYPCUMSOAQFAEBQSFQ3FI2QOAIAAIDQYHJMGM2A

I've seen this happen about 2-3 times sporadically, and both players can see the affect.
