Duplicate Hardware Identifiers being ignored

Currently using Endpoint Configuration Manager version 2207.  I'm imaging computers with a usbc dock with it's own MAC address.  I'm placing this mac address inside the Duplicate Hardware Identifiers option within Hierarchy Settings so that it will ignore the duplicate MAC when I reimage the machine.  However, this is not the case.  Even though I've set the Hardware Identifier MAC to auto resolve conflicting records, I'm not being advertised any images due to the system finding the MAC existing on a machine already.  Configuration Manager is ignoring when I add a MAC to resolve conflicts.  When I delete the object, then I will receive an advertised pxe image and able to rebuild proving that it's not resolving the conflict.
