Jobs data (MySQL) damaged

*Description of issue: Hello. Not so long ago, a very strange event happened on my server, the jobs data was mixed and damaged, it happened after updating the plug-in from version 4.15.5 to 4.15.11. I noticed that in MySQL the names of jobs in Russian are displayed as “???” and suggested that the problem is this. But in a recent dev-release, this problem was fixed, but the data on the server did not return to normal.

I tested this dev-release and found that the names of the jobs that display as “???” do not affect anything and I don’t know why they are recorded in the database.

The screenshot shows that some jobs are displayed 2 times, but also I noticed that the jobs that I used were reset to zero, and the jobs that I did not use, on the contrary, went up in level. Everything is exactly the same in the database.

I thought this was all related to the problem (https://github.com/Zrips/Jobs/issues/813) that was solved recently, but it is not. I’m scared because I don’t want to lose the data that was accumulated by the players, but I don’t know why it happened and how to solve it, please help.
