ender 5 plus lead screw problem

[cliff200400]

have been using my ender 5 plus for a wile now with minor leveling problems but now i have a problem with the lead screws the left lead screw takes the bed higher than the right side not sure what has happened and not sure if I can just adjust that side or if I will need to do a hole recalibration here is a picture of the difference between the left and right sides
