How to Decrease the size of this hit box of cursor or minions?

Can someone please help me decrease one of these hit boxes?

When I play the game, and point the cursor to the ground and right click to move, since the (invisible) hitbox of the minions are so big, i end up attacking them instead of move to location. I can't even tell my champion to stand next to the minion because the ground next to the minion is considered the minion itself. It's as if the hit box of the minion is almost twice the size of the minion.

From the pictures, you'll see my cursor turning from the arrow to a sword, indicating that if I were to right click, it would attack the minion that the cursor is not even on. This affects my gameplay greatly as I cannot navigate through the minion wave the way I want to. I have tried changing the screen resolution to all available settings and it doesn't change anything. I tried decreasing/increasing the size of the cursor, it doesn't have an effect. I know there is a setting somewhere where I can toggle where it only targets champions but it is not a solution I want to explore. I hope I am not the only one that has this issue. Please help if you can
