Steps to reproduce: 

1. Schedule a test list and edit it to be recurring minutely, hourly or daily. 

2. Once the series appear in the calendar, double click any of the items and choose to edit the series. 

Expected: The Recurring pane to display what was selected initially.  

Actual: In the Recurring pane selected will be Weekly despite of the fact it was Minutely/Hourly/Daily initially selected. The value how often the task to be repeated will not be the default (once a week) but will be the listed  previously. (if selected to run a test list in every 15 min in edit mode it will be in every 15 weeks) 

Note: If Monthly or Yearly was initially selected the appearance is as expected in Edit mode.
