Hello @beatrizgonher,
We apologize in advance for our delay in responding. After investigating this issue further, our plugin does not support translating text with WPML yet. Instead, you can directly edit the page with Elementor because WPML creates a new page for the translated page.
The previous method may not synchronize between the translated and original pages. If you like can you tell us which widget you want to solve? so we can create a filter hook to support translation with WPML (temporary fix).
For example, you can add the PHP code in the link below to your functions.php
. After that try to make changes in Elementor to refresh the translation. After that, you can try to check the translation again in WPML. This code only applies to Icon Box widgets.
