Hi @sireagroup
Could you please share the code you used to debug it? If you need to get the value from an attachment, please check this page out: https://www.advancedcustomfields.com/resources/how-to-get-values-from-a-media-attachment/.
If you want, you can also use a gallery field on your custom post type so you can set which images you want to show up on that post.
Thanks 🙂
