Time on "Week View" not calculating properly

When on the "View Week" screen, the time totals for each day are incorrect. See attached photo. On Wednesday, I have logged 2 hours of project time. Wednesday also shows 30 minutes of Zimbra calendar events, which I have not logged time on. However, the hours at the top of this column read "Hours: 2:30/2:30", which is not correct. It should say "Hours: 2:00/2:30".

Same occurring on Thurs. and Fri. as well. Leslie checked her "View Week" screen and told me the same issue was happening to her time totals also.

This issue may be tied to the other issue I was having with recurring Zimbra calendar events showing on every week's schedule instead of monthly/quarterly. The 30 minutes of calendar events on Wednesday shouldn't be showing on that day, as they only occur on the first of the month and quarter.
