Hello,
I have same problem. I have created completely new page, without any content, just added shortcode for the list and I have this problem. So there is no duplicate entry on the page. But I’m using Multilanguage by BestWebSoft. This one works in a way that it’s taking default language and if there is nothing translated for other languages. but strange is that there it’s working. ??
I hope that you can find some solution soon. If you need please contact me and I can try to help you.
My problematic part on site is https://www.lvl0.eu/en_US/lvlo-live/ and for example this one is working https://www.lvl0.eu/de_DE/lvlo-live/ even there is empty content, which means it’s displaying original content.
