We have a problem while editing MS Word that only user that last opened document for edit can save his/her entry.
User 1 opens document for edit, user 2 after her and user 3 after him. User 2 sees that user 1 is editing document, user 3 sees that users 1 and 2 are editing. But when users save their entries, only entry from last user 3 in this case are visible.
Versioning is enabled.
I should note that this happens in library where we added our template word document with quick parts that are connected with library columns.
