Calls wont change status colors on map

So for me, what I do when I get a large call (ie. Gas Station Fire, Burning Machine, etc.), I tend to put more than whats necessary on the box to save some time. When I do this, I also might queue a unit to go on another call once the box clears. But when I go and cancel a unit from the box, itll set it to status 1 (which should happen), but the next call that it was suppose to respond to still has the yellow status symbol as if it were still in route to the call.

Thats the thing though, no other units are reponding to that call
