eM events disappear sync'd with a public calendar

My events created in eM save and sync as private events and eventually disappear from the eM sync’d calendar.  I am saving events to a public calendar on an exchange server.

I can create the new event just fine in eM Client.  It seems to sync and is visible through Outlook but as a private event.  I do not check the “private” option in eM Client.  If I drag the event to a different day or otherwise refresh within eM Client the event will disappear. (still visible in Outlook)

Other posts in older versions seem to lose events with no resolve too. I have 7.0.27943.0
