Just finished Potomac Event Center on Challenge Difficulty with 3 other players and the Damage Dealt/Team Damage numbers seem way off. The 2nd player only had 32 kills which was 16.5% of the total kills, but had 413M damage, which was 68.4% of the total damage. Even though two players had twice as many kills the 2nd player from the left had almost twice as much damage as the two combined. See screenshot:

I've seen this errant behavior intermittently. It doesn't happen every time. I'm in the habit of looking at the detailed summary every time I finish a mission and I think I've seen this happen 2 or 3 times.
