Turret kill only 3 minions but the others do not

Hello, i have problem.
When I start the game, the minions start running, how to get under the tower, so the tower kills only three but the others do not and will leave them alone, As you can see in the video, it kills the first two and then the next one a little further
Where is the problem? I need the tower to kill everything under it and the players but I don’t know how to put it together
