Trouble With Voicemeeter Banana

Hi. I'm trying to set up voicemeeter banana for separating out browser, mic, discord, game etc sounds.

I have followed a few tutorials but always encounter the same problem. The game sound (and any other non-isolated sounds) play through 'Voicemeeter Aux' which I am trying to set up for Discord only. No sound plays through 'Voicemeeter Vaio' like all the tutorials show.

Does anyone know why that is? Any help would be great. Thanks!
