Can’t set key binds

I aim with shift and sprint with right click in every shooter I’ve ever played (including the past 3 battle fields) I’ve never had this problem where I can’t swap those key binds, but now it won’t let me clear shift to set it to only aim, it has to be both aim and sprint, and same with right click but vice versa. Would rather delete the game and both waste my money than learn an entirely different way to play than how I play any of my other games. Game looks awesome and if this is fixed I’ll likely get it too, but it’s not worth It if I can’t play it like I play every other shooter
