[تم الحل] Unable to translate products

Background of the issue:
I am trying to translate products via the Translator on my site الرابط المخفي. WPML was already active on this site in 2021.

Symptoms:
Every product shows an exclamation mark with the status 'published 2021/10/01'. I am unable to edit these translations or translate them again; they seem to be stuck.

Questions:
What can we do to resolve the issue of translations being stuck?
