Move order instead of attack order

as you can see in the image, unit GD31 is going to the city where the 22 infantry units are waiting, however, the game shows an order of movement when it should show an order of attack, probably because the user sent them by moving instead by attacking command, however, i can't know either they gonna attack or not, my only option is to go to diplomacy and check if they are at war, that's an odd way to check if a unit will attack another unit
