ISSUE EHF + POLYLANG

Hi, I have the following issue. I have installed the plugin Elementor Header and Footer on the website. The result has been excellent. However, I had to add a second language to the website with the Polylang Plugin. Then I have the problem that the header menu duplicates. Investigating the code I have detected a class which I am managing via CSS to hide that unwanted header that is generated. It is a mess because the end customer to use the site and for example create an entry in the Blog, it comes with a duplicate header and we must necessarily create a CSS rule on our side to patch the problem. Some idea to give a definitive solution to the problem. The class that is added is:

.ehf-header #masthead

Thank you,
