In the Kills panel, the Loss count icon shows 1 less for some entities.
For example:

In the above picture, I lost 2 turrets (as evidenced by the 2 ghosts) and 2 bots, but the panel displays 1.
I appears that the icon is displaying empty for 1 loss, 1 for 2 losses etc. Below is what it shows when you lose 1 bot:

To test, I decided to kill some of my own entities. Before, the Kills panel had these values:

Then I killed 1 Steel Chest and 1 Contruction Bot. Notice that in the 1 minute panel (below), you can see in the left side that I killed 1 of each. In the right side, only the Chest displays the number 1.

In the 1 hour panel, only the Steel Chest display the correct loss number, the Construction Bot is showing 1, but it should display 2 because we already had 1 loss in the 1 hour panel. See:

The Kills side appears to display correct numbers, only the Loss side is counting empty as one.
