Sorry, tried to answer what I could.

I would suggest contacting support about Bar settings, especially if you can provide examples.
As for the tracks loading where they do, this is what I see, and I think this is also still buggy, but mine is a bit different. I get 'RC' charts after the others at the bottom .. your RC tracks seem to be up in the BB tracks. (RC seems to be RealCharts but I don't see any good reference to be sure)
At least your RC tracks seem to show the associated RT in the name .. mine just show up with minimal labeling, and in a different location (see below).

Both of us get RTs listed after the 1st 8 BB (MIDI) tracks, but like I said, once in RB I usually discard the 'BB Tracks' feature right away, so I don't really notice the Bar Settings in RB.
My track order when I Open an SGU file in RB is below


Hope that helps.
