Storyboard Pro Radial and Motion Blur Glitch

Hi guys

The Radial and Motion Blur tool seems to be bugging out on me and is producing weird, abstract geometrical patterns instead of just blurring my drawing. Regular blur seems to be working fine tho

I have the latest version of Storyboard Pro and I’m on a Windows 8.1 with 16 gigs of RAM

I’ve attached a series of jpegs to show u what I mean
