The reason for this issue is that the Record Detail component populates the recordID associated with the object for the page template, so this component will not work for this use case. The Record Detail component is a component that displays the fields and values of a record on your Experience Cloud site. The recordID is a unique identifier that specifies which record to display. The Record Detail component uses the recordID associated with the object for the page template, which means that it can only display one record per object per page. For example, if you have a page template for Account, you can only display one Account record on that page using the Record Detail component. To display multiple records of different objects ona page, you need to use other components, such as Related List or Record List.
