Basically, when the default language in JIRA is switch to German and the user profile language is set to English, JIRA will display mix language of English and German in the project administration screen.
JIRA 7.0.0 (JIRA Core or Software)
- Set the default language in JIRA to German (under General Configuration)
- Login in as another user and then set the profile language to English
- Access the project administration screen
The project administration screen display in English language only.

This behaviour is actually a regression from JRA-28392.
Currently there is no known workaround yet.
