Tracks and Channels are not the same in S1. Bus is only a channel and not a track hence it does not show in "Track" inspector.
However, you do have the option to make an automation track for every bus channel in S1. In preferences make sure, "Automatically create automation tracks for channels" is checked. Then for every Bus channel in the console you'll have a corresponding automation track in arrangement view, which will show up in the track inspector.
