The appearance of my pages comes back as at the beginning in a random way

[Poulpiquet]

I have a recurring problem on my site. Obviously I built all of my pages with Elementor.
However, it happens randomly, that some pages lose all the layout (color, margin ...) but when I open it with the interface of Elementor to modify it, its appearance is good and I just re-save it to get it back.

Do you know what might be the source of the problem?
Is it linked to the cache?

(Sorry for my english and thank you)
