Hello everyone! I'm new here, so I'm hoping that my problem is an easy fix and that I'm just overlooking something obvious.

My goal is to make some print-worthy renders so I tried out the "Advanced Rendering Plug-In " and I've been very happy with the results, except for one thing! There's a blue line that appears on some of the surfaces with both the "fast" and "best" options. What am I doing wrong?

Please excuse the poor room layout; I threw something together quickly to test render some images. I'm linking a a version of a saved render and a screenshot of the program while the bug is in evidence:
