Hi!
Just when you create the translated form you have to access your data base (the way depends on your host provider, here is through phpMyAdmin), note in the table UserDefinedForm the ID of the translated form, go to the EditableFormField, find the rows (a row equals a field) corresponding to the translated form and change their ParentID field to the ID noted before. That means that you will link the form fields to the page they belong to.
I hope that it applies to your problem and it helps.
Best regards,
Juan
