Why does the calendar show leave over weekends?

When a Employee takes leave that spans over a weekend, the leave calendar shows the leave on the public holidays and weekend days.

Example:

The Employee might be a employee that needs to submit leave on weekends and public holidays if they work a 7 day week.

This is why the "dots" continue across the weekends as well as public holidays.

When leave is submitted over a weekend, the Employee can see on the leave request that the total days deducted will be less than the total days in the calendar. 

Is the Employee is a 7 day work week Employee, and the Switch on the Employee profile is deactivated the Employee will have days deducted for the weekends as well.
