Melee damage in stadium not working

In stadium melee damage increases when you buy perks that boost Weapon damage but for heroes like DVA and Junkerqueen the melee damage does not increase with weapons damage. This is giving an unfair disadvantage for people who play these heroes like myself with DVA where I don’t get as much value with my melee build as other heroes like genji who has a really good melee build which doesn’t have this bug.
