I converted a world from a spigot server with the version 1.13. I copied all files from world_nether and world_end into the world folder bu I didn't replaced the files. Now everything works fine exept the enderman spawning in the end dim. It also just doesn't work on the main island. When you teleport to f.e. 0 100 1000. the endermans spawning behaiviour ist normal. Sometimes some enderman are spawning but this takes a while.

Check a world that has not been touched my modifications at all, if it works fine, it is a result of having used spigot.
Spigot still modifies and makes changes to the world, invalid. Otherwise, your issue is probably MC-139338 anyway.
Problem may be due to the Spigot, in which case it's an invalid report.
