Duplicating groupwise 8 calendar entries

[jr40usa]

When I send an invite to a user, it first shows as a calendar invite from me and blocks the appropriate time. However, a few hours later when I review the users calendar, the invite has appears a meeting and a posted appointment, I don't understand why it is showing as both a meeting and a posted appointment. Please note I have permissions to the users calendar.

Thanks in advance
