Error after defeating some opponents in GAC

At the end of a battle, after defeating some of the opponents (this time it was taking out Jabba's allies, leaving a lone Jabba), I get the Defeated, defeated 3 enemies- Forfeit or Submit screen, I hit Submit, and then I get a "This Grand Arena timer has run out" error, or something like that. Then it exits the GAC, and when I go back to it, it shows it as a loss, with that team wasted, but without showing those enemies as defeated, so then I can't go in and take down the lone remaining enemy. In the current round, this happened against Jabba, in the last round, this happened against a Rey team, where I even took out GL Rey and was left with just Rey Jedi Training, but after the reset, I still had the full team to contend with. So this is two GAC rounds in a row that I'm losing because of this error.
