Landscape does not contribute to Global Distance Fields

Dear Epic Team,
in 4.21.2 the Landscape does not contribute to the global distance field anymore. It is not visible when Visualize/Global Distance Field. I realised it because the DistanceToNearestSurface does not work anymore with the landscape.

I checked it against 4.20.3. In this version, both the distance field of the landscape is visualised and the node is working (tested it with a simple material that lerps two colors based on the DistanceToNearestSurface node).

I hope you guys can fix it fast.

Yours sincerely,
Felix
