Received 5 Banners for Winning a GAC Match

I was doing a GAC match, Traya vs JML, and taking out JML came down to the last second. I was spam clicking bottom right where the ability should be, but because of the insane lag from the update I think my action registered but by the time the turn actually started on my screen, the time had run out. So the final screen shows Defeat, 4 banners, but JML is dead. After I backed out, the scoreboard shows JML defeated yet I only got 5 banners for killing 5 units instead of 63 or whatever I should've gotten. I'm guessing the lag caused desync between the live battle and the actual scoreboard where the live battle thinks I timed out due to lag but the scoreboard knows I didn't? I've attached pictures; JML is gone, but my banner count is at 80 and I had 75 from my first battle on the other wall, so I only got 5 here.
