Problem with share in AD group to some of the users

Two users can’t see the shared folders with the groups they belong to (Active Directory Groups).
I have tried to delete/re-create all shares, disable/enable the users, remove them from the groups then re-add without any result. Other users are fine.
Coincidence or not, they are the last users (alphabetically) of the groups that don’t get the shares with the group they belong (I don’t know if there are more users with problems not identified).
Nextcloud 18.0.4
Someone has an idea to solve this? Thank you
