chances are we resolved the issue in the latest version, so i doubt it was a fluke, and these guys if they still had the problem would of gotten it working as well.i'm not sure if it's of any help. it's kind of late to re-post to this, but I was struggling with it also. I went into AE2 and just selected "ranged" and weapon type "none" and suddenly my character picked up a much much higher level (rare-blue)gun from a quest reward and equipped it. maybe a fluke. i'll re-post if it turns out to be one.
