[Resuelto] WPML -> Translations not showing needed strings.

Background of the issue:
I am trying to translate strings from the Woocommerce EU VAT Number plugin on my website, which is in Dutch by default. I have automated translation active.

Symptoms:
When I select strings for translation, I receive a message that they are not in the site's default language and won't be translated automatically. However, when I go to the 'WPML -> Translations' page, the strings do not appear.

Questions:
Why are the selected strings not appearing on the 'WPML -> Translations' page?
How can I manually translate the strings if they are not showing up?
