Calendar Invites being deleted out of Shared Calendar on local accounts

Im having trouble with event invites from a shared calendar.

We use a shared calendar to send out event invites, the shared calendar is also on local machines for each user. When an invite gets sent out and someone declines the event it deletes it out of the local persons shared calendar but keeps it in the person that creates it.

On Version 7 of eM Client, event invites use to be put into a personal calendar and the shared calendar would still be visible on your local machine, you could still see the event but you just weren’t attending. With V8 it would seem that this is not the case.

Any Suggestions?
