Can no longer seem to separate my Focusrite inputs in Voicemeeter (after an update(?)

So, I use a Focusrite solo for my guitar and XLR microphone, and they seperate by left & right inputs, which means my microphone is permanently transfixed to the left earphone unless a program manually centers it (discord does this), but whenever I'm simply recording audio through video or something it doesn't do that and it's permanently left. I used to use Voicemeeter to fix this (Go into system settings and make the input strips match then separate them in my inputs), but after I reset my PC about 10 months ago (?) I redownloaded Voicemeeter and it seems the UI has changed into something that seems harder to manage and I can no longer separate my inputs? I did used to use a 2i2 and now I use a solo so maybe that was it?? Please help if you can! Thanks.

New UI for input selection
