Masks Not Showing

[Lindsay32934200yzsk]

None of my mask layers, along with the overlays, are showing on my image in the Develop module when editing my images. I can create a new mask but when I apply it to my image you can't see any changes happening. The density is set to 100 and the preset "Amount" is also set to 100. I'm updated to the latest version of Lightroom Classic and I've tried uninstalling and reinstalling LR.

Please post a screenshot illustrating the problem. You did set an adjustment slider to something other than zero?
