Sometimes only able to select faces

Clicking same face doesn’t work for me (4.20.0). Clicking off and back doesn’t work, still selects face. What’s going on?

It appears that brush actor is indeed selected, and if I scroll down in “Details” I can adjust its properties, but this is annoying. My workaround for now is to just hide “Surface Properties” group in Details so I can see “Brush settings” one.

I also notice that for instance when clicking on stair brush, if I click on an edge (between two faces) it gives me what I want, just selects brush. But obviously this is not an ideal way to select thing.
