Thank you. Something so simple.

Here is the image

The paint brush tool behaves normally on the pixel layer. Here is a screen shot of one example. Not sure how to post a screen shot.

I have the opacity and the flow both set to 100%, and all I'm trying to do is to remove the adjustment layer effects from parts of a photo. With a Black and White Layer it should be readily obvious.

I can't paint on an adjustment layer with paint brush. To verify, I started a new project with one photo, and added a Black & White adjustment layer. If I select the paint brush tool, and set the color to black and attempt to paint out any part of the image with the adjustment layer selected, nothing happens (same with white). Adjustment layer is not inverted. Interestingly, if I use the flood fill tool, it behaves like the paint brush should, except it paints everything. I have tried this on several different images with the same result. I am on Affinity Photo 1.5.2, on a Mac on the current version of Sierra. I have looked at other similar posts which verify what I'm trying to do should work, but there must be something I'm missing. The photos I'm using are all pre-processed in Lightroom.
