Ah, I see. That is intentional. The Jungle Raid map includes the Stealth Component with the enemy faction set to unaware at startup. This means that they will not act until they are made aware, by the player either moving into their line of sight or making noise close by. If you want to disable this, select the grid manager and find the Stealth component. Remove the enemy faction from the unaware factions list.
