Skins not working in a 1v1

Hello,
when I start a multiplayer 1v1 match sometimes skins for all of my units, my augment and my announcer changes to default on it’s own without me changing or doing anything.(Sometimes everything works just right, so when I start a next game all of the above is back to my normal settings, then a game or two later this happens again…) How can I solve this problem?
