Hi Trevor,
Thank you for your reply. While I was preparing everything for you I decided to give it another go at trying to fix the issue I was facing, and I was successful.
So, in order to avoid both languages showing up on the translated form on the frontend I just had to manually add the fields to the form. It’s pretty automatic, to be honest, with the “Browse Values” option. I believe this happened to me because the custom fields have the same slug for both languages.
Well, all is good for now, thank you so much for your availability. Feel free to close this ticket.
Have a great day,
Andre.
