PgcEdit SAYS THAT:

WARNING:"
The number of VTSs stored in VIDEO_TS.IFO (3)
doesn't match the real number of Title Sets stored on disk (1).

You should manually copy all files related to VTS 2-3,
or restore the backup.

PgcEdit can also assumes that there is only 1 VTSs.
Warning: If you do so, there is a risk of navigation errors!
Check your DVD carefully! (Use Info -> Calls Cross References)
Should I assume 1 VTSs?"

This has happened because your copy is missing 2 title sets. Since they're missing, I'm willing to guess that you can't get them. You can answer "yes" to that question. Any menu navigation that references the missing title sets won't work. That is what it is trying to tell you.
