Position of the 3D image and its cross section do not match

Nice to meet you.
I am a student and my English is not good. Please forgive me.
I have imported an X-ray CT image into 3Dslicer in DICOM file format and displayed it.
I have imported 799 images sliced in the x-axis direction, 1024 images sliced in the y-axis direction, and 1024 images sliced in the z-axis direction.
However, the position of the 3D image and its cross section did not match. The plane shown at the bottom of the 3D image in the attached image is the red cross section.
I would like to be able to see where in the 3D image the cross-sectional view is located.
I would appreciate it if you could enlighten me.

Operating system:windows
Slicer version:5.6.2
Expected behavior:
Actual behavior:

Can you add some screenshots to illustrate what you are seeing?

Thank you for your reply.
I think I have uploaded the attached photo. I hope you can see them.

Is it possible that there is a deformable transformation on the volume? Look for this icon in the transform column in the row of your volume in the Data module.
DeformableTransform

If you have this, then you can fix the display discrepancy by right-clicking and choosing the Harden transform option.
