Error Message: 'Ddl_ConferencingPolicy' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value

Regarding the issue above, this occurs when following has happened:

You create some Conference or other policies on backend.
You create a service plan and include the policies which were created in step 1.
You modify the backend and delete any of the selected policies (which were selected in Step 2).

To fix this it is necessary to Re-Sync All policies, but make sure that appropriate policies matching the SPLA type do exist on backend prior to performing the Sync Policy operation.
