It seems that your MR volume axes are not aligned with patient anatomical axes. It’s not a problem, Slicer just shows slice viewers aligned with anatomical axes by default. Click “Rotate to volume plane” button in the slice view controller to align slice viewers to volume planes:

In the treatment planning software, did you draw contours with variable distance between them?
