Evolution event level bug

Ok So I was just adding some skill shards to my max level Phantom Eddie, and when i left the my team tab, I got a pop-up giving me awards from the current evolution event mission to 'Max level your 5* characters' even when I did not level anyone up.

It seems like when you add a skill shard to someone who is already max level, the game counts this towards the progress of the 'level up characters to max level' missions, I am not sure whether this works for toons at 4* max level but something I guess to consider during this evolution event
