Binds in the game are little bit strange

Recently, I decided to completely reassign the controls in the game for myself. Starting with aircraft engine control, ending with manual gear shifting on a tank (it’s just more convenient for me to control movement over rough terrain).
However, I ran into a very strange problem. Scrolling in the game CANNOT be reassigned normally. For example, for Plane RB, I use the mouse wheel for the weapon selector. BUT, together with the way I choose weapons, the acceleration changes. It’s the same in tanks. I wanted to assign a change in the shooting range to the mouse wheel, as it is more convenient than on the keyboard. But my camera zoom is changing.
And yes, if you REMOVE the bind, CHANGE the bind - the mouse wheel will perform its standard function. Zoom/Thrust.
And this applies not only to the mouse wheel. The roll and pitch axes of the aircraft are also directly linked to the mouse and cannot be changed. AGMs cannot be assigned to a mouse, even with extra buttons.
I do not know if this is a bug, limitations, or a problem of the game? Maybe the problem is with my mouse/PC?
