Export Relation Custom Field (ACF)

Hello

We paid the Pro version of All Export and we are very satisfied.

Today we tried to export the content of a Relation field (made with ACF). This Relation field is in a Custom Post Type we created.

When exporting in CSV or XLS, the Post title and the Taxonomy of the post are ok.
But there is a problem with the Relation field of the post. The export show the Relation field ID instead of the content.

How can we make it work to have Relation field content and not the Relation field ID ?

Thank you
