Adjustment brush: "Erase" turns to "Add", making it impossible to erase brush
I'm trying to erase some adjustments from an adjustment brush that I've applied. I click Erase as usual, but as soon as I click the image with the eraser to erase the area, the selection option becomes "Add" again, and start painting brush instead of erasing it.
Additionally, when I try to add/remove brush from a gradient adjustment, nothing happens when I click Brush.
I've just realized that this happening today, and wasn't an issue before.
