No Colour Picker on HSL Panel on LrC ver 11.5

No Colour Picker on HSL Panel
LrC Ver 11.5 on MacOS Catalina 10.15.7

I have been running Lightroom on the single app 1Tb plan but decided to change back to the photography plan with LrC and Ps apps installed on my Mac. All went well but I notice that in the HSL panel there is no longer a colour picker tool. I have viewd various turorials on Adobe and youTube and all show the colour picker appearing in the HSL tab, leading me to believe that there is a problem with my version of LrC.

As yet I haven't gone down the uninstall/reinstall route in case this is a new 'feature' in the HSL panel.

Any help greatly appreciated.
