DayPilotCalender - css Styling -- Overlap of "White" area over its container

Hi Dan and Team

In a previous posting:

https://forums.daypilot.org/Topic.aspx/3360/css-styling-calendar-and-scheduler-daypilot-controls

I asked about styling of the calendar and scheduler controls...

All is well with the scheduler control, my issue is with the calendar control...
Please see the attached image

Please explain why the "white" portion overlaps the outer container?

Thanks & Regard
