In Confluence, it is not possible for two pages to have the same title in a single space. As a result, Scroll Documents adds a prefix to every page in a version of a document to work around this limitation. When saving a version, the version name is used as the default prefix, e.g. if you have chosen a version name like - 1.0.0, then the prefix will be (1.0.0).
But there may be situations where you would like to change this prefix. E.g.
If you choose to rename the version, or
You would like a different prefix scheme
In which case, you can use the Change prefix option to update the prefix of all pages of a version in bulk.
Changing the prefix for a version updates the prefix of all the pages in the document version.
Navigate to the Document Manager
Click Scroll Documents from the Apps section in your space sidebar.
From the Document Library, click the document card of a document.
From a page in a document, click Document toolbox and click the cog icon.
Navigate to the change prefix dialog
For the version you want to edit details for, click ••• in the Actions column and click Change prefix.
Add the new prefix in the 'prefix' text box, and click Save
