Can't change Sound Class volume


I created my project in the version 4.21 and after i switched to 4.22 everything still worked,

until just now. For my Audio Settings in the Main Menu i use Sound Classes to change the Volume of all Sounds but not it won’t work.

In 4.21 it worked and in the first week in 4.22 it just broke and don’t work anymore, hope you can help me.

I used Set Volume before in 4.21 but since i use 4.22 it’s not showing up. When i started the engine the Set Volume nodes were just gone
