Philip,
We found the bug, and it was with how we read the database and get all the information out we need. This will be fixed in the 4.1.2 release (due out in a few days). If you want to fix now, you can make the following quick edit to your existing installation.
You'll need to edit: /administrator/components/com_jfbconnect/models/request.php.
Around line 42, you'll see a big MySQL query. This needs to be updated to look like:
SELECT r.*, COUNT(n.jfbc_request_id) send_count FROM #__jfbconnect_request r LEFT JOIN #__jfbconnect_notification n ON r.id=n.jfbc_request_id GROUP BY r.id ORDER BY id DESC
The change there is that the "GROUP BY n.jfbc_request_id" is now "GROUP BY r.id".
Thanks for the report,
Alex
