Sorry, if that came across as hostile, all I was saying is that it's really simple for you (with the disc in hand) to determine the correct playlist yourself using CloneBD.
I don't have that disc here, but even looking at the log file, I see only 3 candidates for feature playlists: 423, 425 and 427.
CloneBD obviously auto-selects 427 - you're stating, that it's not the correct title (you didn't say based on what property), whatever it is, it's definitely a valid one (maybe an extended feature, maybe directors cut/comment, I don't know, that's much easier for you to find out).
Then right below that pre-selected title, there are 423 and 425, everything else on that disc doesn't qualify for a feature film.
Just look at those two (CloneBD's preview player) and whichever appears to be the one you prefer, just select that one.
CloneBD makes this really easy.
Also: 423, 425 and 427 all are "correct" playlists. Which one you choose is a matter of personal preference, so your question can't really be answered by anyone but you.
EDIT: actually, CloneBD may not be showing 423 at all, as it appears to be identical to 427 (CloneBD hides duplicates), so you probably even only have two playlists to choose from.
