Landscape has no mesh distancefields

Me and a friend has worked on a project. On his computer, the landscape has mesh distance fields (using visualize, mesh distance fields). On mine the landscape is completely black, while his has a white glow. After experimentation all my landscapes, new and old have no distance fields.

We both have “Generate mesh distance fields” and “compress distance fields”. We have also tried different scalibility settings (epic).

Is there a way to force generate them? Is there something we’ve missed and need to do? Or is this a bug with ue4?

There appears to be a bug with it and isn’t even showing up in 4.21 for me.
I posted my own thread here https://answers.unrealengine.com/questions/855986/421-landscape-not-part-of-global-distancefield.html

4.20 and 4.18 it worked as intended, so not sure of the what the cause is outside of a bug with distance fields.
