@MitchellRichters-4091 Thanks for posting in our Q&A.
For this issue, I have done the test in my lab. It shows as same as yours. The value of "hardwareIdentifier" shows null.
Honestly, I'm not sure if it is an issue or it is by design. To get more accurate help, it is suggested to create a premier support ticket. Here is the support link:

Hope everything goes well with you.
