Hey @daanniel.art ,
The field that you are trying to map to the text (Authors) is a multi-reference one and not a plain text field, hence you are not able to see it as an option to map, so it is not a scrolling issue in this case.
In order to map the ‘Authors’ field, add a collection list element inside the insights-item element and select it’s source as ‘Author(s) (Multi-reference)’ as highlighted in the screenshot below.
Inside this collection item, you should be able to add a text block and map it to the Team Members collection’s Name field accordingly and it should populate the authors name for that particular Insights item.
Hope this helps.
