Cant remove Events created by blackberry.pim.calendar.createEvent

[splatterb0y]

I cant remove events within the calendar that are created by blackberry.pim.calendar.createEvent.

Here is my sample code:

blackberry.pim.calendar.createEvent({
    "summary": "Fancy text",
    "start": new Date(ui.result.datum), 
    "end": new Date(ui.result.datum),
    "location": "-",
    "allDay": true,
    "reminder": 0,
    "transparency": blackberry.pim.calendar.CalendarEvent.TRANSPARENCY_FREE
}).save(function() {
    blackberry.ui.toast.show("Erscheinungstermin im Kalender gespeichert.");
}, function(error) {
    blackberry.ui.toast.show("Erscheinungstermin nicht gespeichert.");
});

I can remove them trough the calendar on the DAC but not on the Z10.
On the context menu there is just a button to share the event and not to delete them.
Both have the OS Version: 10.1.0.2342
