FullCalendar.. events.. where remove Event excludes more than one

I have a difficulty using fullcalendar.

When I will delete a record or edit. I get an event object.

And whenever I delete something it ends up excluding other events that it should not. on my console there is always more than 1 event.

Another example: I click on an event.left this event and did no action with it. edit another event and end up excluding it. it deletes the previous event and the current event.
