I have escalated this ticket to our 2nd tier of support so our specialists can look deeper into this issue. I will get back to you as soon as I get more information.
We encoutered this issue again recently ; it appears to be linked to inner paragraph links. A workaround which helped me was to update internal link independently after searching them through the research bar.
Btw, can you tell us if there is an update about this fix ?
I'm glad you found a workaround. Our developers are still working on a definitive solution to this issue. I'll get back to you as soon as I get feedback from them.
