Hi @dweb
Please keep in mind that the custom fields is stored in the wp_postmeta table. Could you please make sure that All Export Pro can process this table?
Regarding your second question, I believe it’s possible but you need advanced PHP and JavaScript code. There’s an old tutorial that has a similar topic, which you can find here: http://www.bobz.co/dynamically-populate-select-fields-choice-in-advanced-custom-fields/.
I hope this helps 🙂
