When adding favorites to timesheets, values were also added for days outside the period:

If a timesheet period ends in the middle of the week, e.g., April 1, 2025, values were incorrectly entered in read-only columns when adding favorites. These values could not be deleted, resulting in errors when totaling the hours for the task.

This bug has been fixed so that only the days within the period are now filled when adding favorites.
