Some of my photoshop brushes are not working. In the image, I use the same brush for brush tool and eraser tool. The texture works fine when I choose the eraser but when I switched to brush tool, the brush texture is not working. Some brushes have this issue while others are not. (like 20 brushed out of 50). The brushes that have this issued will have the pen pressure sensitivity greyed out. Also, the brush sample picture is weird too. I don't know why it looks like that. Other brushes look normal.
