Recurrence Editor - Incorrect formatting on Sunday

[Lee Stevens]

Using the Recurrence Editor to create a RecurrenceRule outputs Sunday as "Su" in the BYDAY clause.
The scheduler does not display these  "Su" occurences when used on a Weekly frequency. For some reason, Monthly works fine. 

Changing the weekly rule to "SU" fixes the issue. 

Output of Recurrence Editor, calendar does not display the Sunday occurence:

• FREQ=WEEKLY;BYDAY=Su,MO,TU,WE;INTERVAL=1;

Fixed rule, calendar displays Sunday occurences correctly:

• FREQ=WEEKLY;BYDAY=SU,MO,TU,WE;INTERVAL=1;
