grants are set to 0, when Player left the server and joined again

Server Implementation

Paper

Server Version

1.20.4

Describe the bug

Everytime I give a player with the command /p grant add .... some grants, they will set to 0, if he leave the server and join again. They will set to 0 at the moment when the player joined. During he is left it is still there.

To Reproduce

1. /p grant add PLAYER
2. /p grant check PLAYER = 1
3. player leave Server
4. /p grant check PLAYER = 1
5. player join Server
6. /p grant check PLAYER = 0

Expected behaviour

I expect that the grants are still there after leaving and joining.

Checklist

• I have included a Plot debugpaste.
• I am using the newest build from https://www.spigotmc.org/resources/77506/ and the issue still persists.

Anything else?

Start by reproducing the reported sequence with /p grant add, /p grant check, leaving, and rejoining on Paper 1.20.4 using the linked debugpaste for context. Trace the grant persistence and player-join handling; done means grants remain 1 after the player rejoins, with a regression test covering the sequence.
