Defined zone shows as slightly shifted when I test run a video clip

Hi all, I've noticed something strange in Blue Iris which I can't quite figure out. I define a zone for one of my cameras using a live preview image where I paint or clear the bits of the picture I want covered or uncovered by the zone.

When I then go to view a clip and enable the 'Test run video through motion detector' option, areas which are not in the zone are blacked out, which is fine, but from that I can see that on the clip, the blacked out areas are shifted to the right a bit so it's not quite what I setup in the zone settings.

What is the cause of this and how do I rectify it?

Thanks in advance.
