Hi, thanks for the prompt reply!
I've already clicked on Force Bass Track To Simply. (With Real Tracks I typically do that anyway just to keep the bass player simple.

)
I've Erased the track, regenerated the track ... same thing.
Here's an interesting piece of information. I copied all the chords (CTRL + C) and pasted them into a new SGU file thinking that if I start from scratch (almost from scratch), the problem will go away.
For the last two bars where I want Dm/D (to circumvent the problem) ... I can't write Dm/D and have dm/D appear. I clear the bars, go to enter Dm/d,Dm/D ... and what appears is just Dm Dm ...
I don't see an option to attach a file here. I will upload this file to my web site ... and perhaps someone here might want to take a look. I should add that all tracks are muted except for bass and drums.
Here's the link ...
