When I get too far (maybe 50ish blocks) from my Iron Golem farm in the server, the Zombie, that I both named and put into a boat, will despawn. Same thing for my Enderman farm, but that time the Endermite will despawn right in front of me maybe 20 seconds after spawning it. I even made the Zombie and Endermite persistent using commands. Attached is the list of plugins in the server.

We've tried everything to stop this from happening. First we thought it was a MythicMobs problem, then a Paper problem, then a CMI problem, but when we tested those theories on a local server, the results didn't happen - every time the mob that was in the boat would stay there after travelling thousands of blocks away and going to the Nether, and the mob outside the boat would despawn like normal (none nametagged).
