I converted from DataVault to 1Password following the converter instructions. 17 of my items converted as Logins and ~450 converted as secure notes. I looked into the CSV and it is unclear the difference in the file.
1Password Version: 6.2.333d
Extension Version: Not Provided
OS Version: W 10
Sync Type: Not Provided
