Language switcher: “is-editor-iframe”

Hi,
I had noticed this issue recently, but then it disappeared again.
As you can see I have the language switcher in my menu, but it oddly enough links to https://citationstyler.com/?is-editor-iframe=1723022072&post=10
I first thought it’s some caching/optimisation issue, but with everything turned off, incl. Cloudflare, the issue persists.
Would you be able to help me troubleshoot this?
The site is using Blocksy and Brizy.

Thanks
