After Server Restart entity dupe

When my server restarts, the entities are duplicated. They are always set to position zero, but the previously placed ones remain in place and completely new ones are created.

I checked the data file and the position is not stored correctly there; it always says 0 for all of them.

It doesn't matter whether I have changed a position or not.
