Version shared document nextcloud different from version in onlyoffice

For some shared document, we don’t have the same version when we download the document from the nextcloud web interface (old version) and the edited version in onlyoffice.
If we do an occ file: scan of the document owner, the versions are synchronized.

Do you have an idea of the problem ?
Nextcloud 16.0.1, app onlyoffice 3.0.0
