the filters are now translated, thank you so much, but the solution you give me to translate slugs doesn't work.
When i follow the steps you gave me for translate slugs, i saved changes, and there aren't any changes applied, i don't know why. But if I go to WPML>String translation, and i follow the same steps (i take the slugs and change to spanish as default language), and i return to WPML>Configuration>Post Type Translation, the slugs default language has changed (to spanish); however, i translate the slug, save changes and the changes has no applied.
You're correct, the change of the slug languages and translations are not effective in the WPML -> Configuration -> Post Types Translation section, because this needs to be done first in the WPML -> String Translation module.
Therefore, in order to properly change the language and translate the CPT slugs, please do this through the String Translation page. You can even switch the slug language there, and then translate it into the WPML -> Configuration -> Post Types Translation section.
Kindly give this a try and let us know if you still face problems. Thank you.
