Excel exporter doesnt show data in the sheet

Hi, I have an issue with the Excel exporter. It looks like it is configured correctly. It is creating a document and a sheet with the name I configured it to be. I also configured some attributes and made them headers as well. I can see that the attribute contains data so that should be fine to. My problem is that I don't see anything in the sheet. No data and no headers. PS: I updated it to the latest version and refreshed Mx Objects.

If you include any data from associations in your export, check that the JOIN TYPE is set to LEFT JOIN (on the Associations, constraints and sorting tab) unless you are sure there will always be data for all your records in all of these associations.
