Click on calendar non aligned with grid


we’re experiencing a strange issue with calendar.
It shows existing events correctly, but when it comes to right-click to create a new event, or double click, there is a 15 minutes gap between the point where we click and the event time.

In this image there is an event from 12 to 13 that shows perfectly, then we right-click excactly at 12:00 to create a new event but logging the actiondata it shows 12:15
scheduler_ev_oncontextmenu = scheduler.attachEvent(“onContextMenu”, function (event_id, native_event_object) {
var action_data = scheduler.getActionData(native_event_object);

The image shows everything, the existing event, the right clich and the console.log

What could be wrong?

Thank you

I tried to reproduce your issue in the following snippet: ;
but it seems to work correctly to me.
Probably, it should be related to Scheduler configuration, but it is hard to suggest what might be wrong as I don’t see your code.
Please, add your configuration in the snippet above and make sure that the issue is reproduced there.
Then, click on the Save button and send me the link. Or send me a ready demo with all the necessary JavaScript and CSS files so that I can reproduce the issue locally.
