Steps to reproduce:

1. Open File > Build Profiles

2. Create a build profile and add a player settings to it (press Customize player settings)

3. Change Default chunk count, Default chunk size and Override in Other Settings > Shader Variant Loading Settings

Actual results: 

When changing the Default chunk count and size, it's changing the value globally (for all profiles and project settings) and not per profile.

Expected results: 

The default chunk count, size and override should be changed per profile
