Woocommerce title not changing

Hi,
Im using gtranslate (paid version) to translate from Italian to English.
On the page https://amarantocollection.com/en/product/atlas-of-diversity-parte-1/
Parte should be changed to Part.
Ive used the editor “?language_edit=1” after the url. And it works. But when I refresh or use another browser it does not change.
The website translations also work intermittently. So will stay on IT and wont change to EN.

The page I need help with: [log in to see the link]
