Website jumping back to previous version with strapi content the most recent

Hello! I have noticed this happening twice already and am not sure whether this is a Strapi problem or something else.

I have a website that strapi is managing all the content of, and I have updated the front page for some time now to a new slogan. However, every 1 week or so the front page will jump back to the old slogan while the strapi content remains the new slogan (so it is not like strapi jumped back as well).

Is this common? And how should I try to look into this?

Thank you.

It happened again over this past weekend.
