I hope it's ok to post a couple of different issues.

1.) In Admin UI some of the navigation points show the application var, instead of the translated text. This looks like:
 
application.adminBundle[session.dmProfile.locale].CacheManagement OR
application.adminBundle[session.dmProfile.locale].COAPITools

We've set Deutsch (Deutschland) in our profile and de_DE in admin/Config File/general/LOCALE

2.) We're using the mollio template type C, which fits our needs
perfectly. We've created a lot of navigation points and HTML pages
beneath HOME in SITE. All of them have been approved and unlocked. After pressing
"View" I can see the site as intended. But after loging out of the
administration, only HOME and Support are displayed in our project. What am I doing wrong?

3.) Letters with umlaut, like Ä or Ö or Ü get displayed wrong from time to time. It seems like the more changes we make, the worse umlaut letters are displayed. E.g. Ä is displayed as Ã? and after a couple of changes/updates on objects it looks like Ã?Â?Ã?Â?

Thank you for your support.
