BlackBerry Travel and Calendar

I installed BlackBerry Travel and it picked up my two flights from my email correctly. It also added both flights to my Calendar. I had to delay the second flight by a day and received a new itinerary for it. BlackBerry Travel picked up the change, as expected. Recently, I noticed that the second flight has disappeared from the Calendar. Is there a way to tell BlackBerry Travel to "push" this event again out to the Calendar?

I'm not sure, did you try poking around in the menus? Either via a swipe down while Travel is open or the more (three dots) menu.
