Static Lights Dont Create Shadows

I followed a video to copy Swarm from a previous version of Unreal which was 5.5. Taking it from the binaries and placing it into my 5.6. It doesn’t give and error and says its all competed, not having “Lighting needs to be rebuilt XX” but maybe it’s still not fully functional? Sucks because I like some of the things in Unreal 5.6 but just want to use Static lighting for the time being at least.
