@droftarts Thanks for the explanation! Ok now it makes sense because I am running DWC 3.4.5 and it never worked.
I have to agree with @jay_s_uk that it's a bit pointless if both do the "same" thing. Looking at the dev-version, both buttons are now active only when the mesh compensation is active. And yes you can disable the bed calibration as it just resets the bed probing as described in the G Code reference but for this to be useful it needs to be active as soon as a calibration is active. But then again you can just home the printer and it has the same effect. Don't get me wrong but I feel like now it's more confusing than helpful. But that's not my place to decide.
