I can confirm this happens on my Mac was well. I believe it is because of the tie-in with the system audio.
You can set a preset for your patches so with just a click of a button everything will patch back just like you like it. Look under Fairlight/Presets Library. In the "Filter By" section select Global Presets. Select your mic set-up and save that. Now when you create a new track you just select the track preset and hit apply. That should work for you if I remember it correctly.
