V12 Leave Control Panel Bug

Hi everyone, as per the title of this topic. I encountered a bug in Leave Control Panel. As shown below, I am allocating Annual Leave for employee in C1 grade, which is the highest grade; only 1 person at this grade. But the system allocated the leave to all employees. Similar problem when I allocate via Employee field.

P.S. I didn’t encounter this if I allocate via Designation instead.
