This just happened to me in a standard event. We went 3 games and in game 2 and 3 I could not sideboard any cards. It would remove cards if I clicked the "minus" button, but I couldn't put anything back into the deck. I had to wait until the clock ran out and it autosubmitted the original decklist.
