I recently installed opensuse leap 42.2 and configured Kontact to work with my Google Calendar. Now I have the following issue:
Every time I boot my system, a window appears (Reminders) and shows me my old reminders from 2014! That would not be a problem if I were able to hit the "Descartar todo" (Dismiss all?) button, but I cannot interact with the window. So I am not able to dismiss any of those alarms neither select one. Do you know if this is a known bug or just caused by the huge amount of reminders from the last five years? Do you have any idea, how I can dismiss those reminders?

Thanks for your help,
