D.va Gladiator skill keeps reseting position

I’ve been playing today with D.va and I usually put the Gladiator’s medalion or whatever name it has to the slot 3. Every time the mecha dies or respawns the medallion slot changes back to the default one and you need to move it again over and over for all the game (d.va itself also has to be moved again, but at least the pilot one reamains on your selection).
