Kyle ink brushes stamping at beginning of line

[SheridanLugp]

I want to use kyle's ink brush set, but for some reason most of the brushes stamp at the beginning of the line. Any ideas why this is happening and how I can stop it? It doesn't happen if I move the brush quickly, but that's not always a solution because I like to be slow and deliberate with my lines.

There was a problem I believe in Photoshop Pen support like that. I read it was fixed in 21.2.1 

July 2020 (version 21.2.1) release

• Grid lines become too thick when zooming out while the Show Grid option is enabled
• Layer leaves a duplicate when moving to adjust position on the canvas
• Modifying a smart object leads to unexpected size of the object on saving
• Brush spots created at the beginning of a stroke when using Wacom
• Resolution doesn't show in the quick information pop-up in the image window
• Some Hebrew fonts do not work after update to the latest version of Photoshop
