I have just recently downloaded the GECK and am making my way through the tutorial. I am currently working on the Set NPC/Patrol tutorial. The problem is; that when I try to place an XMarker or XMarkerHeading it won't display in the Render Window though it does display in the Preview Window. Also I skipped forward and downloaded the finished-up-to Navmap .esp from the site instead of starting from scratch. Is this a settings issue or something more?

Ok I fixed my hidden markers (durp) but now the lvlraider marker won't interact. I even deleted it from the cell but the marker for it remains persistent in the render window.
