When you create a new scope in the Password Server you are not able to assign it to a new Vault.
The Scope will be listed in Admin > General Settings > Scopes
The Scope must be added to a Role that the Vault creator has access to.
Note: The selected Scopes will show a Black line under the description once selected.
Add the Scope to the Appropriate Role.
