Ah, yes, I've just tried AD and now I recall that it has some special behavior.
It has a mix of outputs: each drum can be sent to a mono out; but the OH's, Room, and Bus outputs are always stereo. Furthermore it doesn't allow you to pick which output a drum is sent on, when you pick "separate out", it just goes to its dedicated output. And finally, the master bus is drawn (in their GUI) as if it were the last 2 outputs; but it is the first 2 outputs which follows the convention of other drum plugins. This is a case where you really have to understand the plugin's working before you undertake a multichannel setup.
To accommodate this plugin, you'll want to create a stereo master output, then 10 individual mono buses, and then 3 more stereo buses for OH, Room, and Bus pairs. And finally use the grid to connect it all up.
Perhaps someday we'll make a dialog to do this process for you; but at the end of the day it's important to know what you are doing. To paraphrase Einstein: We can make things as simple as possible, but no simpler
Here's a quick video that shows the steps to add the plugin, add the required buses, and configure the plugin to use the individual outs for the kick drum:

Regarding your comment "I get a feedback loop in the master", I'm not sure what you mean, but note that in my video I disconnected the Instrument track from the master bus (Mstr) because we are sending the first 2 outputs to a bus called "AD Master" instead. That might not be strictly necessary but I think it makes it clearer to have ALL the outputs on buses, rather than have some of them in the instrument and the others fanned-out.
