Manual Bed Leveling Assistant huge values returned

I have not created a height map yet. I am trying to set up my Capacitive NPN switch and the suggested steps include to first manually level the bed. I have done that by hand, now I wanted to get the Manual Bed Leveling Assistant working so I can dial in the bed level as best as possible before creating that height map.

Do I have the steps wrong?

Probing twice the same point?

Ok, first off I want to thank this community for always being willing to help out.

I think probing that one point twice that @BoA pointed out was the issue. I updated my bed.g file and all seems good now.

;M561 ; clear any bed transform

You may want to uncomment this, because you would want any mesh compensation or other bed surface alterations to be canceled when doing the leveling.
