I have noticed this bug reappear with Rooms overlapping after Auto Scan is complete and an adjustment is made straight after.
I had reported this issue on older version of app this link below and it is marked as complete but it has reappear on new version of app.
"After successfully completing an auto scan some minor adjustments may need to be made from time to time or some new rooms added after the initial scan is complete. As soon as adjustment is made (like moving a room) all the rooms overlap."
