I haven't noticed this before (it may have been happening for some time), but in a VBO report it shows users who have both an Exchange Online mailbox and Exchange Online Archive consuming two licenses. We have 70 VBO licenses, and counting all the rows in the report equals 70, but should only be consuming 65.

All the documentation and forum posts I read mention users are licensed once whether you are backing up mailboxes, archives, onedrive, teams, SP sites.
Is there a simple fix? Or should I log a support case?
Thanks in advance
