Bitdefender Central Has Difficulty Recognising My Phone, Which Is Now Listed Twice

About a year ago I installed bitdefender central on my phone - which, at the time, had Avira for malware protection.

Since then, I've removed Avira and installed bitdefender. My phone is now listed twice in the list on bitdefender central: once as a Nokia 6.2 which has bitdefender installed, and once as an unknown unprotected device. How do I reconcile the two?
