Onboarding MDE with Defender for Cloud (Problem)

Hello Community,

In our Customer i have a strange problem.

We onboarded with Azure Arc server and activate a Defender for Cloud servises only for Endpoint protection.

Some of this device onboarded into Microsoft Defender portale, but not appears as a device, infact i don't have opportunity to put them into a group to apply policy.

I have check sensor of Azure Arc and all works fine (device are in Azure Arc, are in the defender portal and see them on Intune (managed by MDE)).

From Intune portal

From Defender portal

But in difference from other device into entra ID exists only the enterprise application and not device

I show the example of device that works correctly (the same onboarding method)

Is there anyone who has or has had this problem?

Thanks and Regards,

Guido
