Add second MAC address to computer object

I’d like to create a computer object with udm that has 2 MAC addresses (LAN and WLAN). With only 1 address, it works as expected. After that I can add another address manually without an issue.
But if I try to create the object, it doesn’t work properly. It does not create the DNS entries.

How to fix this? Maybe create the object first and then with a second step modify the object? If so, how to do that?
