Custom field not showing in custom post view

I have a custom post type. With ACF I have also created some custom field. Now when I go to the back end to create the CPT all the custom field will display properly in the CPT view.

However when I use gravity forms to create a CPT all the custom field values will not display even though I configure GF to publish the post when I submit the form.

The only way I could get the post to display the custom field is to go to the back end and press update. I would like to have all the custom field value show up when I submit the gravity form. Help is much appreciated.

Do note that the front end of the post was designed with BB

Did you happen to ever find a solution for this? I am currently experiencing the same issue.
