[BR] Parallel City (BKT 145). Chaotic Swell (CEC 187). I played

Parallel City (BKT 145). Chaotic Swell (CEC 187). I played Chaotic Swell on my turn. My opponent followed up with playing Parallel City. On Chaotic Swell, it states that "the new stadium card will have no effect," but it did anyway. It made me discard until I had 3 benched Pokemon. This is most likely a bug, and it might have cost me this game and many more, so please take the time to try to fix this :)
