The masking feature has been removed from under 'Details'

The masking feature under 'Details' allowed for better control of sharpening (and also noise reduction). I used it on all my raw image. I has now been removed. Please see the attached print screen. There is no Masking feature under Details. This feature disappeared after I updated to 12.0.0.270. Very disappointed as this really helped reduce work flow. I would like to see back.
