No "802.1X Password" generated in keychain when push Wi-Fi policy(scope=system) from MDM server

When I push a Wi-Fi policy from my MDM server, if I use payload scope= "User", then I will get 2 keychain entries auto-generated; if payload scope="system", then I can only get 1 keychain entry.

I have "UserName" defined in Wi-Fi payload, it will be responsible to create an "802.1X Password" keychain entry, but it does not work when set payload scope = "system": UserName host / xxxxxxx

Can any expert help look into this? Why the "802.1X password" is not generated when payload scope = "system"?
