As far as I see you have disabled the B&W panel. Try to activate it with slide switch.

You may have set Profile to be Camera Monochrome. Try setting it to Adobe Monochrome:
When the profile is set to Camera Monochrome, the B & W sliders won't appear. Others have complained about that:
Adobe Camera Raw behaves the same way, so I'm guessing this is by-design.

If the profile chosen outputs pure monochrome picture information, then the downstream processing has no access to any hue, and these sliders become redundant (having nothing to work from).
If OTOH a profile is chosen which leaves the colour in. then the B&W conversion can be set to vary its tone response according to those different hues.
I prefer to go one step more, leave the image in colour mode, but rather than using B&W mode I leave the image in colour. Then I set all the Saturation sliders in HSL panel to zero, producing a monochrome appearance. Now the HSL Luminance sliders work to the same effect as the B&W sliders otherwise would do, but every other colour-specific adjustment remains active.
LrC is outputting an RGB rather than a monochrome image anyway, and even if fully monochrome processed e.g. Tone Curve or grading can still reintroduce some hue information, hence the selection of B&W / Colour working 'treatment', is in effect moot.

So that begs the question why Adobe doesn't define the camera-matching profiles Camera Monochrome to behave the same as Adobe Monochrome?

I guess, one answer to why this may be different lies in the dread phrase "camera matching"! If you imported a camera generated JPG that had been taken in monochrome mode, this would retain zero scene hue information that could be made use of in subsequent processing. This Raw profile is apparently aiming to mimic the exact same outcome... (grin)

But the Adobe Monochrome profile has a defined starting point that can be modified by the sliders, just like the color Adobe Standard profile has a defined starting point. So it should be possible to implement the Camera Monochrome profile to have a different starting point (which approximates the camera's black-and-white setting) but still allow the sliders to operate, as with Adobe Monochrome.
