Calligraphic Lines Automatically Thinning

[Mister22354279p23u]

I'm using the calligraphic brush in my drawing, but whenever I lift my pen off of my tablet (Huion Pro 12), the line immediately thins into a consistent width. How do I fix this?

Hi is that custom made brush ?

[Mister22354279p23u]

Yes, but it also does this for the default brushes as well.

Did you check whether the Size option has the Fix value or Pressure?

It has pressure- the line looks normal initially, but as soon as I life my pen from the tablet, the line finishes and auto-corrects to a fixed width.
