@Ricardo Goncalves, Thanks for posting in Q&A.
To solve this issue, you can try to unenroll this device then re-imports the device Corporate Identifiers and enroll device into Intune again, after that, you can go to Intune portal to check whether you can see the device enrolled under Corporate Identifiers.
Also, you can go to Intune > Devices > All devices to check the enrolled devices. This location shows all the enrolled devices and now also shows Corporate as OWNERSHIP of the device.
Or you can manually add the corporate device Identifiers to specify the device ownership.
