Gas Emitters disabled in project?

I’m currently working with Unreal 5.1.1 and I am trying to create a simulation using the 3D Gas Controls Emitter. However, any time I add Gas Controls Emitter to a Niagara script, it is disabled by default, and stays disabled even if I activate/deactivate the node.

If I add a Grid 3D Gas Emitter, it will be active and work correctly, as will Flip Emitters.

Even Niagara scripts that are migrated in from working projects with the Grid3D Gas Controls will not work.

I’ve tried multiple full rebuilds.

Loading Unreal provided templates are also disabled and do not work.

Any idea of what I should try to get this to wokr?
