My brush won’t work the same as before after clicking the “Brushes” section

I have always used a specific brush on photoshop, and to access it I opened brush settings and clicked it from the panel with tons of squares of brushes. Today I decided to test out brushes not from there, but by clicking "brushes" next to it, ( where I selected them from was "brush settings") Now that specific brush that I always have used doesn't look the same and I don't know how to fix it. Each time I click a new brush from the Brushes category it changes its texture somehow? It's just not painting as before, and I tried to add all the settings it had before but it's still different. I don't know how to get it back normally or how to remove the texture that is affecting it. I don't know what I'm supposed to do.
