Thanks for the update.
There should be no difference in how an event is treated if it is moved to another resource/row. I recommend checking your data source to see if the event has a correct start date.
You can also use the browser console to (Ctrl-Shift-I) to check the scheduler object:
If your scheduler is defined like this:
@Html.DayPilotScheduler("dps", new DayPilotSchedulerConfig { ...
you can print the event data by inspecting the object:
dps.events.list
