When changing the "Start of Work Week" and "Hour of start of work week" preferences, the "effort by week" period does not get updated to show the correct work week.
I.E. I would like to start my work week at midnight between saturday and sunday. Since 12am/12pm is somewhat ambiguous, I tried changing the preferences to start the work week on Sunday at 1am. When I try to view "effort per week" all of my effort time for Sunday is still added into the week before.
