UV tile discard does not work after optimizations

Sometimes after optimizations, UV tile discard stops to work correctly. I could not specify which setting is causing this.

Environment
SDK 3.6.1
d4rk 3.7.4
It seems that this only happens during upload, but not in the editor as shown in the following steps:

1. NDMF framework Manual bake avatar
2. VRCFury Build an Editor Test copy
3. d4rk Create Optimized Copy

Before optimizations, row3 column 3 UV tile discard will hide the lower leg of the base model.

After optimizations, UV tile discard settings will work correctly in editor

The first material of combined mesh after optimizations have UV tile discard section enabled.

After upload, UV tile discard is not doing anything

This is hard to be shown by a screenshot. You could see that the knee mesh is visible when the kneesock is on, which is not expected. If I move the camera into the body, could see that the whole leg mesh is rendered.

Here are two trash bin files after optimizations in editor and upload
