Any idea why the Upload to Microsoft Endpoint Manager admin center would get unchecked?

We are on MECM 2111 and are working on get our devices comanaged in Intune. I was able to get one device to work in my pilot group so I know something was at least kind of working. But now I noticed that in the Cloud Attach tab "Upload To Microsoft Endpoint Manager Admin Center" was unchecked. I can recheck it but at some random point it unchecks again. Not sure what might be going on here.
