MTGA inserted one of my sideboard cards into my starting 60 during Qualifier Weekend Day 1 (Explorer, 6/15/24). I drew the sideboard card in one Game 1. During sideboarding, the specific card started in my main. If I moved it out, three copies visually displayed in my sideboard (I registered only 2 copies). Additionally MTGA told me 'deck too small' if I submitted 60 cards post-sideboard with all copies of the glitched card sideboarded out; I was forced to play 61+ in sideboarded games including at least 1 of the glitched card. The card was Unlicensed Hearse.

I reinstalled the client between matches. This did not improve or change the outcome.

I want another shot at THIS Qualifier Weekend before the time is up.

I'm trying to attach images but it says "Could not identify image size". Please let me know where and how to submit those images as evidence of the problem.
