Leave Application half day

It does not work half day function.
System says that I should input 3 dates such as From date, To date and Half day date but it is not allowed to input those dates.
What do I have to do? Please, help me.

You need to provide a From Date and To Date for a Leave Application.
What is your use case?

A day off is no problem.
However, when I have half day off, it does not work.
I checked mark on half day and then I can not save it.

It is work now,
Someone fixed it. Great!

please consider marking this post as solved. Thank you.
