The lower numbered MPLS would reference the feature.
Yes, this is what I see on both disks (working and non-working)

In a Quick-Play backup it is also possible that feature may have IGS (although most of the time it doesn't) -- that's usually for some graphic feature that pops-up upon request. Sometimes it's things like a graphic of the original storyboards or something similar. The PID for that stream would also be 0x1400 (the base PID for an IGS).
Working disk:
00001.mpls refers to 00001.m2ts with no IGS
Non-working disc:
00001.mpls refers to 00021.m2ts with IGS

The out-of-mux IGS for the feature would be named the same as it was on the original disc. From what you have shown me there doesn't appear to have been one, or there would have been four M2TS files in the STREAM folder. If BDEdit shows that there is a subpath listed for the lessor-numbered MPLS, then it would appear that BD-RB kept the reference, but not the file -- which, of course, would be a bug.
This seems to be the case if my interpretation of BDedit is correct .....

What I don't understand is why there is even a menu when there is only one item to be played? Normally a menu is not created for a single playback item unless the hidden option MENU_FORCE_QUICK=1 is established. I assume you have that set in your INI file?
Exactly. It's convenient to insert a "Play movie" button this way.

I'll dig around and see if I can find a disc with out-of-mux IGS in the feature and do a Quick-Play backup just to see what I can find. But, the more I think about it, maybe I should eliminate the IGS subpaths on a Quick-Play backup. There are other possible headaches that could conceivably come out of an IGS stream -- since the commands really have no limit to their actions.
My disc is "Frozen Ground", (Region 2).

Edit:
Another problematic disc was "Game of Thrones" (S1D1, Region 2).
It has no IGS but sV and sA (IM PIP) with makes the disc non-playable. IMPORT removes these and makes the disk playable -- my speculative conclusion only.
