recurring events incorrect dates showing.

using beta version. 1.7.2 beta

Recurring events for X day of the week per month displaying in the wrong day.
ie: event held on the first Saturday of every month
Displaying on first one month second week the next etc..

It appears to be an issue when the date is the FIRST of the month..
ie in months where the first Saturday is anything other than the 1st of the month it is displaying correctly.. - This also seems to affect the subsequent listings.
ie: Events on the 3rd Saturday of each month display on the 4th for a month that has the 1st Saturday as the FIRST of the month..
