Opening redcloth remove MaterialInstance from ApexClothRessource

[ElementaryLewis]

Describe the bug
Tested on WolvenKit 7.2 Nightly 01/2025. Whenever you open one redcloth and save it, it accidentally removes its link to the MaterialInstance (leaving then NULL in that list). You have to assign back in order to fix it, else this will bring invisible cloth in game because of missing Material.

To Reproduce
Steps to reproduce the behavior:

1. Open WolvenKit and one project
2. Extract any redcloth (whether from vanilla or mod)
3. Open it, then save it (doesn't matter if you have modified it or not)
   An example of redcloth is characters\models\main_npc\yennefer\model\dress_01_wa__yennefer_px.redcloth

Expected behavior
The tool should detect the ApexRessource having Materials Instance, without to assign them NULL.

Additional context
I went to test the old WK 6 to be sure, and it doesn't have the issue before. That's where I notice missing Material.

To add more about it. The issue occur as well for w2mesh, though oddly it desync the last material instance in the list.
An example is environment\architecture\human\common\fortifications\palisade_entrance_01.w2mesh. This mesh use three material, and it's always the third/last that being desync to the mesh resource.
