EDIT: Updated with code which outputs the array
Should be noted I have other fields which work correctly, the issue is only with the repeater sub_fields.
// Needs to be updated to be more dynamic i know
function get_flexible_content_sections($name, $option = "") {
// check if the flexible content field has rows of data
if ( have_rows( $name, $option ) ):
// loop through the rows of data
while ( have_rows( $name, $option ) ) : the_row(); ?>

ORIGINAL:
I have a nested repeater field inside layers of flexible contents. The purpose of which is to add images which are outputted to a slider.
The image ID's are stored in the database, but when I try to output them using get_sub_field, this is what i get:
I have build the field group programatically, which works in the backend as seen below. The backend equivalent for the above output:
The entire ACF settings/program:
if ( function_exists( 'acf_add_local_field_group' ) ):
add_action("init", "tryangle_generate_sections_fields");

generate_fields( "indhold224466", $indhold_gd );
}
endif;

if(empty($uniqid) || empty($group_data)) return;
