Header Footer disappear when Polylang is activated

Hi,

I had an issue on my page where header and footer created via the Elementor Header Footer Builder plugin disappeared. After checking in the troubleshooting mode I discovered that the reason is Polylang. As soon as I activate the plugin, both header and footer disappear, and appear again if I deactivate Polylang. Could you help me understand how to fix this issue?

Thanks!
