In 22.11, cataloguing tools were moved to the Cataloguing screen. If you click Help when on the Export data screen, you get taken to this help file - https://koha-community.org/manual//22.11/en/html/tools.html#export-bibliographic-records which is no longer correct. The user then needs to navigate to Cataloguing / Export Data from the menu option on the left. Can the link be updated please?
This has been fixed with another bug now :)
