Strange behaviour in color callibration

Maybe I’m asking a very stupid question. But somehow the color calibration module is giving me unexpected result. This image is shot in daylight. The white balance in the camera was set to daylight.

But when I use the color picker to auto determine white balance, I get this strange result

The thing is, this is all my images. On my installation it doesn’t seem the matter what camera: (Leica Q2 DNG, Z8 NEF, or iPhone (DNG converted via Adobe Camera Raw). It also doesn’t seem to matter what mode I used in camera (auto, daylight or any other).

What I am doing wrong?

When you look under color mapping in the module what are the values??

They should be 50, 0, 0…

Edit:

This is a sticky setting if you ever change it a module reset does not reset this you need to physically reset the values otherwise its as if you are color mapping all your images to the selected color patch…

Note that the target value is not reset when you reset the module itself, but is stored indefinitely in darktable’s configuration and will be available on next launch as well as for the next image you develop. Additionally, the position of the selected rectangle is also stored for ease of use when applying the picked correction value to multiple similar images (see below under “match the target”), though you may redraw the rectangle if the position of the target object changes between images.

If you use the picker for exposure it does the same thing ie its sticky as part of the exposure matching, Just fyi in case that changes or you feel things are off… you might have to reset that…
