[Resolvido] WPML export import isn't working

Background of the issue:
I am trying to export my translations using WPML. The issue can be seen at the following link: link oculto.

Symptoms:
I received a message saying: 'Before importing, your content needs language information'. This is confusing because I want to export, not import.

Questions:
Why am I receiving an import-related message when trying to export translations?
How can I successfully export my translations without encountering this error?
Please check the screencast attached to understand my confusion.
