An issue with Worlds

I have 4 worlds, and I use nucleus to tp between the and I have a world called “spawn” which is the main spawn point. But when I tp to different worlds, it sends me to the defualt spawn points of the other worlds. And for example, I tried this:

When I tp between them, it still brings me to the default spawn of that world. And in the worlds, I just try /spawn- brings me back to the world “spawn” at the spawn point.

Any plugin I can get? to set one default spawn in a certain world.
