The "Top Hostnames Usage" report in my Untangle setup seems to be completely inaccurate. If I start downloading gigabytes of internet data from my PC, the hostname shows up with the appropriate amount of traffic in the other Bandwidth Control reports - e.g. "Top Hostnames (by total bytes)". But my PC doesn't even appear in the "Top Hostnames Usage" report - instead I see other hostnames there with very little bandwidth being used in comparison to my PC.

Any ideas?
