Players can’t be added to set

I apologize for the inconvenience you're facing with adding players to the Buzzer Beater 90 Overall Upgrade Set. To resolve this issue, please ensure that you have the required players in your inventory and that you are using the correct versions of the players. Additionally, check if there are any restrictions or limitations on adding players to the set, clear the cache of the app, and if the problem persists, contact the game's customer support for further assistance.
