Directwave: Why is it playing repeated notes, rather than a single long note?

[Apendica]

I am exporting pads in DirectWave however it seems to be repeating a note, rather than holding down the note for the inputted time. Does anyone know why this is the case? I have posted the pre-render and the post render, where you can clearly hear the note being repeated. Am rendering from Vital. Is there something I am missing here?
