Unreal Studio with SketchUp model - to work impossible

StaticMeshActors of the model, imported with Datasmish from SketchUp, change their position themselves from time to time in the level, for unknown reasons.
Is it a problem of SketchUp or Unreal Studio? Or it is only my problem?

If you are still experiencing an issue with the Sketchup import process, please log a ticket on our dedicated Unreal Studio support site. https://unrealstudiohelp.epicgames.com/s/case-community-page

Thank you.
