404 Errors, duplicated language code on URL

Hi there, I’m using Translate Press and WP EasyCart, I think I have the same issue of this post for product pages: https://wordpress.org/support/topic/404-wrong-urls/

for example trying to access to a single product page from here https://archivio180.com/en/products/beers/

I get an url like https://archivio180.com/en/en/store/stone-ipa/

instead of https://archivio180.com/en/store/stone-ipa/

I can’t understand where the duplicate language code comes from, at the moment I fixed this issue with a JS Patch but this is not a really good option since I get all those 404 pages in my sitemap and that patch I written not works for example while clicking on a link pointing to a category page from a a single product page.

Is there any known method to fix this?

Thanks so much in advance
Nicolò
