"Excel Report missing IDs"

zepho

I'm trying to export a data view/data table file, from a model application dataset.
In the "report" block, the attribute filter type is set to 'all', the 'include special attributes' option checked.
The table consist coloumns of: Name, ID, Prediction, Confidence values, Observation values.
In the results view everything is fine, but the exported excel file is missing the ID coloumn.

Any ideas what might be the problem with the excel file?

Actually I managed to export the data correctly with the writeCSV module, so the problem is solved, but still, it'd be nice to know why the report operator is failing.
