Hello,
Can you tell us more about the kind of document is affected? CryptPad supports a large type of documents thanks to the applications bundled: https://docs.cryptpad.org/en/user_guide/applications.html
Also, where are they hosted? On which instance?
Do not hesitate to add screenshots to your message, it can allow people to better understand what the issue could be. Sadly, at the moment your initial post has very few information.
