Just stumbled across this one, it may be public knowledge. As you know PT<10 has at most a 12 hour timeline (archaic). If you run your Nuendo sessions with 24 hour lengths, the OMF will always have your Nuendo session’s start time even if you tick the “between locators” option. So if your information is after 12:00 you’re out of luck.
Change Nuendo’s start time so everything fits in 12 hours and it works.
We run with 24 hour session lengths because the video folks will switch between 24 hour tc and 12 hour tc at a moment’s notice.
