Same here it seems.
Just found a solution though, select the landscape, check LOD 0 - and other LODs, set them to max.
To fix that further, I was finally able to get a decent response by selecting the individual tiles I was interested in within the landscape manage component section and setting the Forced LOD from -1 to 0.
Hardly a fix, it’s a nasty hack. but maybe it can be automated with Python or something.
