Auto-Mask Sensitivity Inconsistent

Hi All,

I'm in the middle of editing working in the same manner I always do and suddenly auto-mask stopped working. Object/Subject/Range/Etc all work but the Local Adjustments brush is wildly inconsistent. It can isolate intense highlights and random objects but that's about it.

So far I've tried:

- Restarting the computer and program

- Resetting preferences

- Reinstalling Lightroom (Always made sure it's on the latest version)

- Updating graphics (Checked for it but was already on most recent release)

If anyone's had experience with this, please share your experiences and fixes!
