Mirage Not Working As Intended In Firing Range

I play mirage from time to time in the firing range to have a little fun while I am doing a 1v1 against my friends, but it is impossible to trick anyone. In the firing range (with friendly fire off) when I send out a decoy or use my ultimate, it shows the name tag right over it, thus revealing my location and also making it easy to tell that I am the real player because I am the only one without a nametag. Is there a fix already or a fix coming out?
