Dear Syncfusion team,
I was notified by our customers that for some configuration of Schedule task are displayed with backward offset.
I was able to reproduce the issue here (with Syncfusion base/schedule version 22 which we use).
Settings that breaks the display (for example)
firstDayOfWeek - 1
interval - 300 (also for example 50)
slots - 4 (slots 5 works fine!)
On the screen below: task should start at 12OM, starts before 5
