Problem:
It is currently not possible to translate the Ocean WP Footer Template created inside of the Theme Library.

Solution:

Our compatibility team provided a fix that will need to be implied by the theme author into their theme:

Set the custom field ocean_custom_footer_template to copy-once and update the page and its translation.
Go to plugins/ocean-extra/includes/metabox/metabox.php
Find

if ( $meta = get_post_meta( oceanwp_post_id(), 'ocean_custom_footer_template', true ) ) { $template = $meta; }

Add this line after it

$template = apply_filters('wpml_object_id', $template, 'oceanwp_library', true);

Relevant Documentation:
This is a compatilbity issue between OceanWP and WPML.
