When creating a page properties report based on "mentioning user," once the macro is saved it can not be edited at all. The users mentioned do not show up in the edit dialog when it is reopened, even though the filter is working. If the report needs to be edited (add a mention, add another filter), the save button is completely disabled.
Screenshot shows a report that is working to filter user mentions, but does not allow me to see users in the filter, add users or save other changes to the report.
