Painter Texture Cover brushes

Hi,

I'm using Painter 2020 and installed some new brushes. As I was going through some, I can across the Texture Cover brushes. I notice as I'm going across the canvas, the brush ( any in the category ) seems to hit a hard stop even though there is canvas left. Is there a canvas size limit with these brushes? In the image, the top strokes are an oil bristle brush, can paint across the whole canvas. The bottom is a texture cover brush, hit a wall.

Is this normal?
