XP-Pen and Kyle's brush issue

[MannayDesign]

I'm having trouble configuring my ARTIST 22 (2nd generation) Tablet with Photoshop CC 2021.

My brushes don't look the same when i use my Wacom tablet and my XP-Pen tablet. I've put an example image with this message. (the brush used is Kyle's inkbox - rough brush 2k17). It looks like the XP-pen don't deliver the same results as when i use my wacom tablet.

Could you please help me configure it correctly?

By the way, i'm on MacOS Catalina 10.15.7
