Are you sure you have had the queens from the removals? What I do is cage the queen for 3 days then release her. When you do that you increase the chance of them staying.
If I do a removal and not sure if I have the queen. I make sure to add as much brood comb with eggs and larva. Place them on a screened bottom board. Give them a gallon of 1:1 syrup and lock em all in for 3 days. By that point they accept it as home and stay put
