Jira sends email notifications even though the option was unchecked

[E A]

So, every week I am supposed to make a new sprint and move the tickets from the old sprint into the new one. I do it through the bulk-modus. I always uncheck the box that sends email notifications, but even though I do that, after the tickets have been moved, everyone gets emails! 

Also, even though I've been using the proper filter, the "geschlossene" (german Jira) tickets, end up in the new sprint....

Issues move into a new sprint when closing an old one if they are not considered "done".  This is defined by "in the rightmost column on the board"

I have seen similar. Regardless of what you might select for notifications, the Notification Scheme takes priority. The Default Notification Scheme will send email to anyone that is a watcher, the current assignee or the reporter. The only way I have found to override the Scheme is for the user to disable notifications.

Depending on your point of view, this might be considered a bug or as intended.

Could be. 

But do you know why would the geschlossene or the closed tickets end up in the new sprint when I made the selection filter of choosing all but the closed ones 🤔
