Can't change lineup & train players

[annetteleewy]

I'm playing in the league Anglia. From yesterday night, two errors occurred. First, when I changed my lineup, it refreshed. Second, when I tried to train my players, it always told me that a player is already been selected for training. Please help to fix it. Thanks.

@annetteleewy Hi, welcome.
We are collecting all reports about this in one topic practice-bug

Important to mention in there is on which slot you get that error.
What were the exact steps you took untill you got the error and on which platform you got the error.
