"Skipping dirty area creation because of empty bounds" Warning

I use 4.26.1 and got the same errors… basically for all my custom meshes.

LogNavigationDirtyArea: Warning: Skipping dirty area creation because of empty bounds (object: StaticMeshComponent /Game/Maps/ModelTest.ModelTest:PersistentLevel.LightSphere_low_InnerSphere_low_3.StaticMeshComponent0)
