Can't unbind controller left stick button

Can't unbind left stick button from radio. Says it's unbound when reassigning but it doesn't actually do it. I want it back so that I can sprint without using the keyboard.

Hey @KatherineInRed,

Thanks for bringing this to our attention. I'll pass it on to the team, so they can look into it.
Meanwhile, are you able to reset your keybinds?

Has this issue been addressed because I have the same issue?
