### Godot version

v4.0.beta.custom_build [0a9e6e478]

### System information

Windows 10, Vulkan, GTX 960 528.24

### Issue description

This [55420](https://github.com/godotengine/godot/issues/55420) issue seems that it is not completely solved since in the advanced importer the same thing continues to happen.

### Steps to reproduce

- Put a 3D model on the scene
- Open the advanced import
- Disable Auto LOD or whatever you want to change
- See how mesh doesn't change
