Stuck in arena loop

About half an hour ago there were some minor connection problems. I was running arena at the time and once the issue seemed like it sorted itself out I went back in to finish my run. It showed me that I had 1 fight left and I expected it to tell me that there are some connection issues and that I had lost the fight. That's exactly what happened, however, once I entered the arena again after getting kicked out it showed me the incomplete match again. And again... and again. Now I can't grind out the rest of the milestones and ill likely fall short of the bracket I was aiming for as well. Any help appreciated.
