Mobs stop being tracked after restart and lose their MM attributes

Summary

Describe the bug encountered in detail.

Steps to reproduce

Here is a config of one such spawner https://pastebin.com/Y89D0sR5 , you can see that the maxmobs is set to 3 yet after a restart it has 5 active mobs. It doesn't seem to spawn any more after more restarts, but it still does it once and it can overflow the spawners if they have higher amount of mobs to spawn. Version: 1.17.1 Paper git-paper-88 MythicMobs: Premium 5.0.0-snapshot-a0e23ea4

Current behavior

After a restart the spawners ignore spawned mobs, making them vanilla mobs (losing disguise, cmds not working on them etc.), and spawning more mobs in even if it's over limit of MaxMobs set.

Intended correct behavior

Mobs stay tracked and don't overflow the maxmobs limit.
