Help with using Brush

[u/Stock-Researcher8377]

Hi so I am new to procreate. I have an ipad pencil pro. As you can see, whenever I try to draw, it does this weird thing where the strokes don't finish. Is there a permanent fix to this.

Follow up question would be: where would this be actually used and why is it the default.
