Lightbox displays website content (not Instagram content)

Hello, I have noted that on Elementor pages – the lightbox pop-up is displaying website content instead of Instagram content. However, on WordPress pages, the lightbox popup works as expected. Here are some examples from the same website –

Elementor page – https://heathernicolelong.com/
WordPress (blog) page – https://heathernicolelong.com/blog/

I appreciate any insight you can offer. Thanks!
