Problem:
How to display the first item of a Repeatable Field Group on each post?

Solution:
You can create a View that displays your RFG (Repeatable Field Group) items
Add a query filter so it displays the RFG items that belong to the post where you'll insert this view.

Then ensure the View Ordering option is set to orderby toolset-post-sortorder field, in an ASC order.
In the Limit and Offset settings, set to display 1 item, skip 0 items.

This will display the first RFG item for the post where you'll insert this View.
If you drag and drop the RFGs on the post in a new position this will change the View output, and set a new RFG as the "first", and only output item.
