My kills are sometimes not shown in the kill feed - Show all kills = ON

Here's a video from a single round of conquest on Mirak Valley. I have "show all kills" turned on for the kill feed, but sometimes my kills are not shown. There does not appear to be any rhyme or reason for it. Sometimes the kill is far away, sometimes it's close. Sometimes it's a multikill, sometimes it's a single kill. Sometimes it's in a vehicle, sometimes it's on foot. This is clearly a bug. Occasionally, I'd like to know who I killed, so I'd like it to be fixed please.
