[Fechado] re translate Spanish to English

Background of the issue:
I developed the site link oculto in Spanish and translated it to English using WPML. My client then modified the original Spanish pages by changing pictures and words. Now, I want to re-translate these modified pages to English and overwrite the original translated pages.

Symptoms:
I can't seem to re-translate the modified Spanish pages to English and overwrite the original translated pages.

Questions:
How can I re-translate modified Spanish pages to English using WPML?
How do I overwrite the original translated pages with the new translations?
