I´m using Magix Movie Edit Pro MX and suddenly a problem has occured. After I have created chapter markers, closed the program and reopen it, the chapter markers are still there BUT every second marker has no contents and does not appear in the chapter menu. If I delete these "corrupt" markers and create new ones, the same thing happenes again after closing and reopening the program. And the reason cannot be that I have created too many markers, as I have created 40 markers. But, perhaps it is a result of the fact that the project at first was 2,5 hours long with more than 100 chapter markers, which I shortened to the final project (1,5 hours, 40 markers) and that the empty space on the timline, after the 1,5 hours-clips, is still there showing that the timeline is 2,5 hours long. And I cannot find any method to delete this empty timeline space.
