The width and height can be changed and are reflected in the preview, but only the thickness cannot be set to the desired size; it will appear thicker than the Spine image.

Changing the language to English did not solve the problem.😫

Overriding the settings does not ensure the correct thickness.😢

Horizontal boxes are the wrong thickness in the 3D Model. For some reason, this problem can be solved by setting the height of the Spine image to be the same as the width of the Front image. Using images with the correct proportions increases the thickness of the 3D Model. If the height of the Spine is set to the width of the Front image, the 3D Model will be the correct size. There may be something wrong with the handling of 3D Model images.
