Description

When we started working with the database to pass the group data to our site, we noticed that the main group of the player is displayed as default in the database, although in fact it is not. In the game, his group is displayed correctly and all rights are present, however, the database is incorrect, which prevents the correct determination of the player's group on our website.
Seeing this problem, I tried to go in and reissue the group to myself, after which it was correctly displayed in the database. However, I have always given myself a group in the correct way, as well as other players, but the group in the total is displayed incorrectly in the database!
What could be the reason?

Extra Details

If I reissued the group manually while in the game, then there were no problems with displaying it in the database. However, the rest of the players remain with problems, although the group was given to them correctly.
