Bukkit World spawns with no Vanilla structures

1.16.1 Bukkit Server:
When i make a world using the Bukkit#Worldcreator:
-Bukkit.createWorld(WorldCreator.name(this.worldName));

The world does not have any vanilla structures even if i explicitly tell it to:
-Bukkit.createWorld(WorldCreator.name(this.worldName).generateStructures(true));

Only other thing i change is:
-e.getWorld().setKeepSpawnInMemory(false);

And for some reason
-e.getWorld().getGenerator().shouldGenerateStructures()
returns false...

I have also looked into the server settings, and found that all the
generate-structures lines are set to true.

How do i make Bukkit generate Structures?
Thanks for any replys.

 

OK so after further testing iam thinking it may have something to do with the server iam using. Iam using a Niterado server, if anyone also uses one would be nice to know if you had/have the same problem.

 

Welp I have been really trying to get this to work, because I badly need this function. But even when making worlds with the multiverse plugin they are without structures, I have checked all the configs in the server directory but there are no settings off in there. I don't understand thoe why even multiverse is not able to generate structures. Does anyone atleast have a suggestion I could try?
