"Add special bind" setting does not appear to be working correctly, as in it doesn't allow you to combine a preexisting setting with for example scroll up instead it just adds it as an extra bind as shown in the picture below. This didn't use to be the case and currently for me for example it's unplayable as I can't adjust some very crucial settings I wish I could. It happens across controls tab in the settings tab it doesn't matter whether the game is modded or not however because of this bug I along with many others can't change settings that would come in handy in for example modded reforger with nvg/thermals.

In summary we can't be adding binds such as
alt + scroll up/down
ralt+ scroll up/down
ctrl+ scroll up/down
rctrl+ scroll up/down
shift + scroll up/down
rshift + scroll up /down

pls fix
