Bed leveling

How or what do I do to fix this?

Firstly I would remove the build plate then check and tighten the 4 screws.

Then run another calibration and see if anything has changed.

Thanks for the reply. I’ve changed out the plastic stanoffs for rubber ones and all is good except the right front. It will not calibrate. I have it completely loose, I could probably take the screw completely out and it still would not make a difference.
