On the Vaults page in AuthAnvil Password Server, selecting a scope that is neither top nor bottom in the list will cause the page to refresh, opening either the Private Vault or Personal Vaults tab if available. The proper scope view is no longer selected after the page refresh.
This is a bug with PWS v2.0.0. This issue is fixed in the current version.
Upgrade your Password Server to v2.5 following this Guide.
