Steps to reproduce:
1. Open the “Unity_Bugs-2” project
2. Open the “Unity_Bug” Scene (Assets → Scenes)
3. Open “Waterfall_Particles_Bottom_vfx” (Assets → VFX)
4. Notice the particles in the Scene view
5. Set Color Custom → Sample Mode → Custom
6. Uncheck the Camera Fade (Alpha)
7. Set Color Custom → Sample Mode → Over Life

Expected result: The “Camera Fade” block’s parameters can be changed
Actual result: The “Camera Fade” block disappears, and its parameters cannot be changed, but it has an impact on how particles look
