the melee weapon dosent work with a controller on pc

[Thiecing_Client]

  Melee on pc with controller dose not work like it use to and you can melee once but after ur weapon comes out you can't hit with it untill you put it away again, so get rid of the ability to hold just the melee weapon and call of duty that thing or fix it so i can use my melee once and for all like every one else can pleas and thank you!
