HOW DO I GET 1 SUBTITLE ON TRK WITH MANY MARKERS? :(
You can't have a subtitle 'intersecting a marker'. It's part of the DVD specification. No authoring software will allow you to do that. It's not a program bug.

You have to have your subtitle end a little before the marker. Then you can add another after the marker. That's just the way it works.
