Wrong website title language in Google results

Hi to the community,

It’s been months now since I tried to solve this issue. Bubble has no answers. Google has no answers. So I try the community.

My website title in Google results regularly (like every month) changes for 1 or 2 days. My website is only in English, but every month it changes for 1 or 2 days. Sometimes in Italian, Persian, or Korean. it’s random. I just don’t understand what is triggering this.

Any idea?
