Same issue here for Xbox on the open beta. I use right stick for crouch/prone and B for melee/melee takedown which is the same thing I do for all fps games which let you change input options. However when I melee in game, I always end up crouching as well despite the fact that B is not coupled to crouching anywhere in the infantry control mapping section of settings. This also means that I cannot mount or use the bipod for LMGs as that function by default is coupled to the same button as melee, and there isn’t any room for it to be set to any other button on controller without an input clash happening.
