Restoring SharePoint 2010 Calendar Events

Greetings,

I am unable to restore the data from previous item versions from a SP 2010 Calendar. When I look at the previous verision, I CAN SEE THE DATA, but it will not restore the data itself to the new version. Help!

For example: Version 5.0 does not have the data, for some odd reason it was removed, however, when I look at the Version 1.0 of that item, I can see the data I need restored. When I select restore, it does move the data to the new version, but when I go to the calendar, it is not restored!

Help!!!!
