Adobe Flash Professional CC 2015 keeps on making straight scribbles when i tap using pen tablet

[ayachiecatz.]

so, this weird problem only happens when i tried to draw with my deco 01 xp-pen tablet. i only tapped a single dot and these strokes appears. i cant scribble anything other than this too. my pen works well in my other drawing softwares.
but its working just fine when im using mouse.
i tried reopening the software, restarting my laptop and still have the same issue
can anyone please help me solve this?
