All the mic inputs are the raw microphone inputs from when the drum samples were recorded. As such, they aren’t receiving anything from other channels, but play back what those specific microphones recorded when sampling the kit. If you want to separate the bleeds, you can create a user microphone channel and route them there.
Do this by opening the Route Instrument Microphones window (in the View menu)
Select the drum you want to move the bleeds from,
Click the appropriate button in the Mixer Channel column (OH/Amb/Room)
Create New Channel
Repeat for each microphone you want to mix separately, into the newly created channel, or separate new channels. After that, you can either route them straight back into the original channel (if you only separated that one microphone, or sent them to separate user channels), to a bus, or out to main.
