Elementor locked with header template

I have built a website with two languages and I have created a header template for each one. When inserting the language selector in the main language everything worked fine but wanting to insert it in the secondary language Elementor Pro does not load me. If I deactivate the Polylang Connect for Elementor plugin, I can enter the header but the selector does not appear to drag it to its position. Any idea what is happening?

Thank you
