What happened?

Im using betterend with nullscape, generation will use nullscape endgen and they works fine, however ive found out a inconsistant biome transition while any biome next to minecraft:end_barrens, other than that works pretty good.
I didnt modfied or change any custom generation, i run all of them as default

There is another wierd thing happened with nullscaple on dedicated server:

1.While bclib have forcebetterxpresent (both client.json and server.json) set to true, level.dat end generator will set to vanilla by default, but when i try to change it to paulevs generator, it'll always automatically revert to vanilla, even if i manually change worlds_together.nbt generator to paulevs it isnt fixed too

2.if i turn forcebetterxpresent to false and do the same steps, the whole level.dat of end generator will be transformed to a biome type that completely eliminate betterend biomes, so the dedicated server world been resulting of cannot have paulevs generator of world type that containing nullscape's biome

worlds_together.nbt:

The first one what ive workaround and the result of level.dat:

The second workaround and the result of level.dat:
