[Closed] I have a few issues with a website and it's use of images, a menu and tables

Background of the issue:
We have built a website using Beaver Builder, Beaver Themes, and the Astra theme. We have created a 'mega menu' for selecting products using the standard Astra menu and an embedded 'page' for the mega menu structure. Additionally, we used 'saved rows' to create content within tabs on the product pages. Link to a page where the issue can be seen: hidden link

Symptoms:
No images showing in the slideshow. A menu that doesn't display correctly in the French version. Table content that cannot be translated.

Questions:
Why does the French version of the mega menu look squashed and isn't central?
Why can't the content with the tables be translated?
