Outlook 2010 Calendar import recurrence pattern problem

When importing Calendar items from Microsoft Outlook 2010
items with Recurrence ( Frequency = “Weekly”, Pattern = “Recur every 2 week(s)”, Days = “Friday” )
are imported as “Recur every 1 week”

I have to investigate it a bit deeper, but meanwhile you could send me the problematic event saved as .ics. Thank you.
