Hello @what_is_love_chik

Does this issue occur for every document you have or it is only related to this specific document on the screenshot? By the way, is it regular DOCX document?
For now, I have made a sample document in the same environment, closed it and now I am waiting some time to check the situation afterwards. If there are any specific steps I must include, please let me know.

Hello!
Issue with comments occurs in documents where I have been making comments since June. The earliest duplicated comments were on 18.06.2025
I can’t share this documents and I can’t say how to reproduce bugs.
I also made 1 test document, but now it’s okay.

Can you check out logs of your Document Server for any errors related to saving of either the file or the changes made to it?

By the way, we have just released new version of Document Server. I recommend updating and monitoring the situation further.
