My problem is that an appointment that covers multiple days is not displayed correctly in Week View (see WeekView.PNG) while it is displayed correctly in the Monthly View (see MonthView.PNG).
As you can see the appointment does not cover the entire box, does not cover all days for his duration and more is moved to the right. The code in both cases is the same.
For more information I have inspected the item and there is a margin-left which, I believe, has no reason to be there. Also witdh calculated element is obviously wrong (see InspectElement.PNG).
I tried everything, but nothing.
Many thanks for the support.
