Having problems exporting items in the Opportunities module. Some of the Opportunities won't show up in the csv export. Out of around 3000 items only about half are exportable. Can not find any explanation or difference between the ones that show in the export and the ones that don't.
It's as simple as that: some opportunities are exportable, other are not showing up in the csv file (I can only export them from the back-end).
Any idea what might be causing the issue and how to solve?
Thanks in advance
