Double Header Issue on Pageload

Hi there. I’m having an issue where upon pageload, there is a duplicate navbar/header, one on top of the other. After a second or two, it disappears.

For reference, I’m using the Astra Theme and also built part of the page with Elementor. This happens on multiple devices, so I’m not sure what could be causing these issues.

If anyone has any ideas, please let me know. I appreciate any help you can give.
