Dicom files exported from mimics do not work properly with 3Dslicer

Operating system:win10 Windows Feature Experience Pack 120.2212.4190.0
Slicer version:5.2.1、5.3.0

I first trimmed the dicom file with mimics24 and exported a new dicom file, which can be opened and used in both mimics and MITK.
However, in 3Dslicer it is not normal, although there is no problem with the threshold selection, but when I click “Apply”, some of the thresholds are missing and cannot be selected, and it also shows weird in volumetric rendering

I also researched this issue, I deliberately applied all the thresholds, and it was clear that the thresholds outside the green box were like lost

By the way, how do I change my avatar in the forum?
