Had this as well, initialy the sideboard and main deck were switched during sideboarding. Once I switched to a different deck, when I was sideboarding, it showed my deck I was playing before. Restarted the game then, as I also wasnt able to just move on without sideboarding.
It then showed the proper deck but when I removed a card from main deck it wouldnt let me add from sideboard...and couldnt submit a deck with less then 60 cards. Gave up after the second time this happend.
