Batwing rotating backwards on left wing

I bought a used 15' Woods 815HD to mow pastures. The right and center blades rotate clockwise as they should.
The left wing also rotates clockwise but the and blades are positioned to cut counter clockwise. There is a decal on the left wing that indicates the blades should rotate counter clockwise. I'm guessing someone did a gearbox repair and installed something incorrectly. Any suggestions would be much appreciated so I don't start a project blind. Thanks
