Muting Mic also mutes the microphone for entire system

[prodtw96]

I like to record sound from myself whilst also in a Zoom meeting. And whilst it will work recording and in Zoom. Whenever I mute my microphone in Zoom. It also mutes the microphone for the entire system. Is there a way around this? 

I have tried with input being my actual microphone, or the same as system and both give the same outcome.
