I have several players who have announced their retirement and are not listed in the staff conversion tab, including one who was there last season.
Can this be corrected quickly please?

Last season, this was also the case for me and, at the start of the season, they are all available.
As far as the administrators are concerned, we don't have the tools to solve this problem.

It should be noted that the players selected (in the federation and perhaps even in IS) do not appear.

No
