Help with video translation in learndash

Hello, I am trying to have my course in two languages, Spanish and Portuguese. My course is based solely on videos. I use the presto player plugin to display my videos that are hosted on Bunny.net.

For the translation I am using the Translatepress plugin and following this guide https://translatepress.com/learndash-translation-tutorial/ where they explain the use of the shortcode to wrap the two videos (Portuguese and Spanish)

In the editor, the video blocks are first the Portuguese video and then the Spanish one

When the user watches the video in Portuguese (first block of the editor), the lesson is marked as completed and the progress is saved. Everything ok

The problem appears when a user tries to watch the video in Spanish (second block of the editor) completes the video but when the learndash button is clicked to complete the activity, the system does not register it, it only reloads the page and does not save Progress.

If I swap the order of the blocks in the editor (first Spanish and then Portuguese) the problem is the opposite, when the user sees it in Spanish and marks it as completed, the progress is saved, if he sees it in Portuguese, it does not save the progress.

I have updated both learndash and presto player.

I have tried in different browsers and the problem persists

I am testing on an alternate user, as an end user
