Ye the addon incorrectly uses the same salt as the original aether dungeon, which will cause the structures to spawn at the same place.
Structure essentials probably just allowed the addon's dungeon to spawn in the same biome, it doesnt change the spawning itself.

If you want to prevent the overlap you can either fix the salt to a unique value as it should be, or enable the minimum distance in structuressentials configs to prevent overlaps(it is disable by default)

Got it, thank you for your reply!
I realized I can use datapack to fix the issue.
