I can't edit the private league

I created a private league, played for a while, then abandoned it. I decided to clean up the list of participants, after which one of those removed from the league expressed a desire to play again, but his status was "Removed". I can't change the status, the player also can't accept an invitation from me. I can't add a player manually either, there is no such function, only send a link. I also can't delete or lower the "Role" of other players. I wrote to support, but they have been silent for a day. Has anyone encountered this? How can I re-add a player?
