The issue I'm seeing is that no fields appear when translating a post type to Spanish. Post type is set to translatable (only show translated items) and set to expert with preferences are either copy once or translate.

Hello,
Thank you for reaching out!
Allow me to leave a quick reply until one of my colleagues takes over this ticket.
The ACF Field Groups should always be set to "Not translatable" at WPML > Settings > Post Types Translation.
The fields of each group will be translated together with each post or page they are assigned to on the WPML Translation Editor when translating the post or page, depending on which setting you use for each field.
Exception:
ACF Option pages will need to be translated by switching the language on the top admin bar while editing the options page.
