Yes, I can confirm I’m also having the same problem with the Cornerstones Exhibition Objectives.
I’ve completed matches with the correct requirements (minimum number of players from the requested leagues) and even won, but the progress tracker does not move at all. It feels very frustrating to spend time completing these matches and not see any progress registered.
It would be fair if EA could not only fix this as soon as possible, but also consider offering some sort of compensation/bonus for the wasted effort and time.
