I'm not in the factory for a few days to check but my thoughts are that you may need to map the export layers by tool not by layer.

And map them from the Defaults, not your assigned tools. ie. Select - "Default Cutting", "Default Grooving", "Default Bevelling", "Default Marking" etc., as this is how they are assigned to the Ductboard patterns when added to a job.

Give this a try and see what you get.
