Why does timesheet show more Time Off balance when compared to reports?

Scenario:
User's timeheet shows Paid Time Off as 4.35 days remaining but the Time Off Balance report show 2.68 days remaining.

Cause:
The User has a weekly timesheet period starting on a Sunday and the timesheet shows incorrect information; is for the period March 27th to April 2nd. When we run the Time Off History report to find the number of days remaining as of March 31st,it shows that the user has 2.68 days remaining as of March 31st. However, on the 1st of every month they accrue 1.67 days i.e. on April 1st, number of days remaining is 2.68 days + 1.67 days = 4.35 days.
