This is currently the expected behavior for RC keys. They're time limited(there's 55 days left), but they still enforce your max license count. We're looking at changing the wording around this so it's clear it is an RC key and not an evaluation.
One other thing to remember, after release, you'll need to get your new key and update that. If your RC key expires, NCM will stop functioning.
Thank you for the info, i will add the correct key when it's available.
