Wordpress Custom fields showing up incorrectly

Hi! I am relatively new to blocs, and I am trying to integrate Wp with SCF,
I created a SFC Post type (Exhibition) with a field group that references another Post Type (Artist) so users can add Artists to the exhibition as a Custom Field (“exhibitions_artist).
I am able to retrieve “exhibition_artist” from a given Exhibition in Blocs using:

%WP_CustomField(exhibition_artists)%

however, on preview the value of exhibition_artists is the ID of the artist, but I don´t want to show the ID

If I query the WP API I can see the rest of the fields on the response:

I can’t find a way to get the title or any other field, Am I missing something? Also, if you notice, the dates values picked up by Blocs app are the unformated ones, can I get it to pick the formated ones?

Thanks for the help!

This is the json response from the API where I can see the rest of the fields
