MySQL geometry intersection gives non-intersecting results

I have a MySQL zip table with the geometric area of ​​each stored as a polygon. I also have a table of regional regions that are polygons as well. I am doing a simple query to find the overlapping area for a specific zip (i.e. Find which area it belongs to), but I am getting returned areas that do not overlap at all.

Here is my request:

SELECT a.*, pc.StateID AS PostcodeStateID
FROM area a
 JOIN postcode pc ON INTERSECTS(pc.Geometry, a.Geometry)
WHERE pc.Postcode = '4065'

      

        
        
        
      

    

Why does MySQL return results that don't overlap? Is there a mistake in my request?

Here is the polygon for zip code 4065:
