Weird shadows on the borders of landscape sections (gpu lightmass)

Good evening. I’m experimenting with gpu lightmass, I need to

bake the lighting.
My actions:

  • I turned off Lumen in the project settings: GI and Reflections set to None
  • turned on Hardware Raytracing
  • turned on the gpu lightmass plugin
  • light sources Directional Light and Sky Light set to Stationary
  • ShadowMap Method set Shadow Maps
  • set objects to the level, disabled the viewport update in the plugin settings and started building the light

After baking, it is precisely that in Play Mode such artifacts appear on the borders of sections of the landscape. There are no such shadows in the editor mode

They appear exactly after rearranging the ShadowMap Method to Shadow Maps from Virtual Shadow Maps. However, with the default setting, the light clearly does not look baked, and the shadows move with the objects.
Please tell me how to fix it.

It seems that the point was that all the project and level templates used World Partition. As soon as I created a level that didn’t use it, everything worked. Even the message “Lighting need to be rebuilt” returned
