The first thing I would verify is that there are no data source filters (they aren't obvious as they don't show up on the data connection page):
1. Right-click on the data source name in the data pane and select Extract Data.
2. In the Filters box, ensure there are no filters.
3. If there are filters, select each filter and click Remove
4. Under Number of Rows, ensure that All rows is selected
5. Click extract
If the steps above don't work, I would contact firstname.lastname@example.org and let them know about this issue as it may be a bug.
