Yes, I noticed this a while ago, but I haven't had time to look into it. It is clearly a bug, probably introduced by me during my last update of the node/link layer, and I am sure it easy to fix. As a matter of fact, I have realized this is becoming urgent even for my own company, as we are planning to use this statistics to measure media quality. I'll try to find time for it during the coming week. (Unless somebody is volunteering of course).
