Default page width has changed to contained layout

Hello,

I’m using Astra Pro with Elementor Pro.

So far, my pages had a full width. I would use the “default” page layout and I never touched anything.

Here’s an example of how it used to be: https://www.colada.fr/faq-foire-a-questions/

But now every new page I create has the contained layout: https://www.colada.fr/test/

What could be causing this and how do I revert to how it used to be without breaking everything?

Thanks in advance for your help!
