Economy Count for Knights Templar is wrong

Season 11, for this game:

I checked the timelines after the battle.

My (fenian1980, Mongol, purple player) economy count seems to match my villagers + traders.
His (Brotal1ty, Knights Templar, pink player) economy count is much less than his villagers.
I believe this is a bug unless I totally misunderstood what economy count represents.
