Absence: Save and Close - why populating on timecard and preventing payroll from processing

Summary:

Why does the Save and Close button populate the timecard?  

When this happens, the payroll team has to go into the timecard and clear an error.  

I understand that there are ways to hide the save and close button - and I'm not asking about how to hide the save and close button.

What is the reasoning for a saved absence to be populated on the timecard given that it has not been actually submitted.

I can see a place for the Save to be useful for the EEs. But if it's not been submitted, it doesn't seem like a good design to add it to the timecard as if it was submitted and approved.
