Exposure calibration

Hello,

I shoot the chart in 3 different modes : spot, central weighted, multizone.First, I expect to have the same result - the camera should select the same iso as the chart fills the frame - and I observe that multizone overexposes.Second, the histogram should be centered in the middle at 50, as 18 % gray should give the average exposure. Am I right ?If I'm right my D850 overexposes a little bit, I have to compensate -1/3 EV in spot and central weighted, -0,5 EV in multizone. I have also observed that I didn't have the same exposure parameters with my D500

Please help.

I didn't find the right solution from the Internet.
