Z axis calibration failing MK3S+ MMU2

I just upgraded my MK3S+ to have the MMU2 unit added and after the successful installation and print I went to do a large print (almost the whole build plate) and I noticed that the back left was messed up. There was a large hole in the first layer with excess filament around the sides. I thought I should recalibrate the Z-axis but now when I try, it lowers too far on the front middle and the back middle detection points. All other points work fine. I'm not sure how to fix this.

Are you sure your bed is flat?
