Hero Chronicles “Is your HERO a villain?” task not working

Hello, I am facing a bug in FC Mobile Hero Chronicles. The task “Is your HERO a villain?” says I need to swap an Aston Villa player into my Starting 11, but it is not completing. I used Buendía first and then tried another Aston Villa player as well. I removed them and added them back again, restarted the game multiple times, and even played matches after swapping them into my lineup. I also made sure they were in my actual Starting 11 and not on the bench. Despite trying all these steps, the objective still remains locked and I cannot claim the reward of 300 Rank Up Tokens. Please check this issue and fix it because many players may be facing the same problem. Thank you.
