Slicing reference file function seems not to work as expected

[SaibotMagd]

I have to slice and rotate the reference because of some quality issues regarding the dataset I'm using right now. But the max parameter of the slice-function for the reference file seems not to work in relation to a min parameter:

  annotation_file, reference_file, distance_file=ano.prepare_annotation_files(
      slicing=(slice(None),slice(None),slice(13,456)), orientation=(3,-2,1),
      overwrite=False, verbose=True);

It is identical to:

also:

is identical to:

In the tutorial pipeline they also used the max-parameter in z-direction and it works, so I think it could have something to do with the rotation. What I found out till now is that the function does the slicing firsthand and the rotation of axes afterward. Could this also lead to some other problems like my distortion issue when I try to align to the reference file? Could it be neccessary to rotate the dataset always in the same direction like in the tutorial pipeline?

PS: if you look at the top pictures, something happened with the brightness. It's actually in the pictures.
