I had tested the Dropbox Backup feature in the past so I know that when turned on my Computers should be added as My Mac (Unique Mac Name). I decided to turn it back on again when setting up two new Macs that I have but the backup now creates the folders as just Mac, Mac (2), Mac (3)
I've gone through the steps of unlinking Dropbox from each computer. Checking their names in System Preferences and also in the Security tab of my Dropbox account. The computer names are correct in Dropbox but the backup feature is still creating the folders as just Mac
