@PratikPB2123
After Christensen-Burley is available again in 3.0, in the Principle BSDF Christensen-Burley is enabled by default,
and there are no Subsurface IOR and Subsurface Anisotropy options.

If you select Random Walk or Random Walk FR, both options are displayed.

In 2.93x and before, neither Subsurface IOR nor Subsurface Anisotropy were available for Random Walk or Christensen-Burley.

These options are only supported for Random Walk, not a bug.

@brecht : These options are only supported for Random Walk,

Hi, please refer the broken and working version images.

in the Principle BSDF Christensen-Burley is enabled by default,

As far as I can see Random Walk is enabled by default.

I guess it happens with a particular .blend file, can you attach it? For me they appear correctly opening a file saved with Blender 2.93 for example.

Added video to clarify the steps. Not specific to any file, I can reproduce this issue with default file as well.
