I had issues for over a week not being able to edit the translations' text. Support could not troubleshoot this successfully.
The problem was not about the length of the descriptions (all within limit), or about any special characters.
It did not help to log in from another device, nor to delete cache, nor to log incognito, nor to use another browser.
What DID help was to delete the translations ("Manage translation"–> "Remove translation"). Remove, then create anew. It's manual work but resolved my issue.
Posting here in case someone else finds it useful.
