Vault allows users to reuse the documents or binders with the Make a Copy option. Why does Vault not use the name in Make a Copy dialog if the document has an auto-naming pattern when making a copy?
This is expected. If a document has an auto-naming pattern, then Vault uses that instead of the name provided in the Make a Copy dialog.
