Wrong times are booked in the calendar of appointments +

I have had many problems with + appoinments . Some have been solved by you but not all ....

Now a new problem surfaced.

When I book service 2 ( Parterapi ) in + appointments for 90 minutes (120 minutes incl break) , an error occurs . The Calendar books 180 minutes. (the correct hours but also the hour before)

Its not a problem for service 1(samtasterapi)

I do not know , but perhaps it is related to this problem:
