Okay so a possible bug has been discovered, using release 1.10.2. So far I have just confirmed it with DVDs as I have not tried BDs.
It seems "stuck" when naming the destination directory. I have tried switching semi-auto, auto, manual.
I stuck in Duke of Hazzard Season 6, Disc 1. It wants to name it DUKES_OF_HAZZARD_S6_DISC_1 - fantastic, thank you.
I then flipped the disc over and it still wanted to save the files to the exact same directory, even though the volume label of the disc indicates DUKES_OF_HAZZARD_S6_DISC_1B. So I forced the B after the 1.
Next I inserted disc 2 - it wanted to dump it to DUKES_OF_HAZZARD_S6_DISC_2 - great.
Next I flipped the disc over to side B, yep, again volume label says 2B but it still wants to dump it to 2, not 2B, so I add the B.

Here's where it gets interesting. When I stick in Disc 3, 3B and 4 it still wants to save it to 2B, even though the volume label is correct! After fighting those 3 entries I insert 4B and it wants to save it to 3B.

I have installed 2 pieces of software since last using MakeMKV.

Updated Nvidia drivers & GeForce Experience
Updated from Windows 10 to Windows 10 Anniversary Edition.

I suspect if anything the issue is with the latter, but why?

Mike promises fix in the next version.

Thanks - actually I had replied to that post but it sounded like that person's issue was different.
At the time I see Mike had NOT replied to the thread yet.
Hopefully since Mike is going to work on it again we can get an "Enforced" name option of some sort... Folder name and title names are to be completely based on disc volume name rather than just sometimes. Sometimes title names inherit the disc name, other times not, thus generic title00.mkv, etc.
