[Resolved] wrong flag for string translation

Tell us what you are trying to do?

I am building a WP theme in spanish and I've already set up the whole WP environment and WPML default language in spanish, so I am adding the php code like so in, for instance, the template-home.php file:

<p><?php esc_html_e( 'Aprende español', 'BHS' ); ?></p>

(which means 'Learn Spanish')

then I go to the backoffice > WPML > themes and plugins location
to find all the strings and after that I go to STRING TRANSLATION

but I am seeing the flags in the wrong position (please find a screenshot attached)

Maybe I am doing something wrong or I forgot to define or declare something?
or it is mandatory to add the texts in the code only in english?

Is there any documentation that you are following?
No

Is there a similar example that we can see?
No

What is the link to your site?
it is a local site using MAMP
