Error when showing schedule time in my personal booking page

In my personal booking page (Sorry if the names are not correct as I have it in Spanish) when creating a meeting ans putting the opion "Using my regular meeting Shedule" (Usar mi horario de reuniones habitual) it works properly from Mon to Thu but not Friday (as this day is only ntil 15). It still shows later. 

I've checked everywhere and my schedule and timezone is updated. What can I do?
