Booking Times

i have this problem:
In my calender i have hours to booking. It has a range from 08:00 to 24:00 h
I set the booking times on workdays 16:00 -22:00 h

Sometimes i need to expand the booking time to 24:00.
Now comes the error, when i have a approved booking in this day (08:00 -22:00) it shows an error, when somebody wants to make a booking after this approved Booking Time. (22:00 – 24:00)

You see it on the 1 February
