Top menu alignment changes with WP Fastest Cache

Hi

I already hat a chat with the Elementor support. But since the problem is caused by this plugin, they can’t help me out: The menu in my header sections becomes left aligned when the fastest cache plugin is activated. As soon as I deactivate it in the WP dashboard and clear the browser cache, everything works fine again…
