Enforcing blank value in Settings Catalog, Local Security policies User Rights

When trying to enforce a blank value using settings catalog to set UserRights it will throw error in Event Viewer.

Example: Settings Catalog - User Rights - Lock Memory.

When trying to use any of the following values you will get an error back, in Event Viewer or in the Intune Policy report.

Example values below.

MDM PolicyManager: Merge of policy did not complete successfully, Policy: (LockMemory), Area: (UserRights), Result:(0x8000FFFF) Catastrophic failure.

Value: </>
(Fails in Event viewer and gives no change on the policy)

Value: <Data></Data>
(Fails in Event viewer and gives no change on the policy)

Value: *
(Fails in Event viewer and gives no change on the policy)

Value: ""
(Fails in Event viewer and gives no change on the policy)

Value: <![CDATA[]]>
(Works on Event viewer gives correct value on policy on the device, but Error on policy in Intune)

OMA-URI Working but not Settings Catalog for same values.

When using OMA-URI: ./Device/Vendor/MSFT/Policy/Config/UserRights/LockMemory

Value: <![CDATA[]]>

*UPDATE*

Still testing values but <![CDATA[]]> works, but an error is displayed on the Intune policy, not in the Event logs.

Using full XML file is currently the only way I can get this to work for both Event Logs and Intune policy, so no errors are displayed. This should not be the case.
