Yes sorry for that. I was irritated by a JIRA bug, when you enter a comment while having a list of reports and then click on a different report, you are asked if you really want to leave the page. In case you click "Cancel" you still see the same report but the selected report in the list (blue background) changes.
Cannot confirm in German, can confirm in English (US), see screenshots.
