Datapack problems! Please help me! (Minecraft)

Dear experts! On one of my worlds, which is used as a world for the server, I installed the "Death Counter" datapack. After transferring the world to a newer version of the server, I decided to delete the datapack, but in the "datapacks" folder it did not find anything except the main server datapack. When using the / datapack disable command, this Minecraft datapack was not found either. All the commands of this datapack are also gone, but the datapack itself is working (on the right you can see the Death counter's boss all the time, the numbers also change when players die). Please help to remove or stop the datapack. If there are no such methods, then tell me at least how to copy the server data so that all the structures of the players are preserved.
