I have a bug with some brushes

Hello everyone.
I bought the ZBrush SKIN Brushes Pack from Pablo Muñoz and I have a problem with some brushes. If I load them from a normal folder, they work perfectly but I added them in Pixologic/Zbrush 2021/Zbrushes, and when I select them inside Zbrush some brush don’t work well. As you can see in the photos, the brush affects the entire surface.
Should I save them in another place?

Hi @Diego96 Welcome to ZBrush Central

The creator of the brush is the man to see.
