RESOLVED

on the page eg. GDPR Request

1. Edit Page
2. on the Web App Part Select Edit which opens "Insert Request Configuration"
3. Set the "Target List" to "Requests"
4. Wait for the SharePoint Auto Save to change from "Draft not Saved" to "Your page has been saved" (next to the [PUBLISH] button
5. Publish the update

repeat on all the pages
