Coliseum - DRYAX T7 can't be finished - HP Frozen

After the new update to the holotable i tried doing my dailys and went to the coliseum, I noticed that i was killing the beasts much faster than usual. I killed one and got the last one to red health but noticed that the progress bar was just stuck at 28%, All the damage i did after that was just -1 and i was stuck in an endless loop since my units was too strong for the beast to kill. I surrendered and i got a message saying i need to restart my client. 

But even after that i still got the same bug when trying it again. At least the daily counted my fight even tho i retreated. A shame tho that i wont gain a rank until this is fixed.

After posting the pic i noticed that the beast is lvl 70 like all my troops so Idk what the problem is. Im on lvl 7 on coliseum.
