MakeMKV crash trying to save missing episode from Great British Railway Journeys

[outlier]

There's a DVD set of Series 1-4 of Great British Railway Journeys. On one of the discs there's an episode that doesn't get saved. In normal mode it reports the following:

Title information
1: 1/1 - 1 chapter(s) 0:00:10 1 cell(s)
2: 2/1 - 1 chapter(s) 0:00:10 1 cell(s)
3: 3/1 - 1 chapter(s) 0:00:08 1 cell(s)
4: 4/1 - 1 chapter(s) 0:00:00 1 cell(s)
5: 5/1 - 5 chapter(s) 0:29:11 5 cell(s)
6: 6/1 - 5 chapter(s) 0:29:20 5 cell(s)
7: 7/1 - 5 chapter(s) 0:29:13 5 cell(s)
8: 8/1 - 5 chapter(s) 0:29:12 5 cell(s)
9: 9/1 - 5 chapter(s) 0:00:00 5 cell(s)
10: 10/1 - 2 chapter(s) 0:00:22 2 cell(s)

The episode that gets filtered out is #9. I'm able to save the episode if I opt for manual mode and specify "9:1-5", though if I use something else that doesn't specify the chapters (e.g., "5 6 7 8 9") then MakeMKV crashes:

I wonder if the different DVD Opening modes have any effect?
