Pen making marks on canvas before it touches the screen

I’ve been using Toonboom for a couple years now, and nothing about my setup has changed, but just the other day, my pen started making marks on the canvas before it even touches the screen. I use the xp-pen pro 12, and this issue only happens on Toonboom…

If you have any ideas as to what I should do let me know! I have a final due next week and this issue’s really making it difficult to proceed.
