Xbox game bar does Not remember volume settings for games and apps

I play Forza Street everyday and while I'm playing I usually listen to Spotify music and I have to lower the volume of the game from Xbox game bar every time I start the game. it's really annoying. I use the Xbox game bar beta and I launch it using Win button + G shortcut. Windows 10 insider fast ring build 18985
