I haven't seen this before.
Seems like the whole model has been rotated on the X or Y axis by 90°.
I assume that your model looks correct in plan and 3D?
What happens if you create a new schedule?
Or export the schedule that works from the other file and import it into the original file.
I can't think of any settings that would affect this rotation.
Close and re-open the file maybe?
