This thread is resolved. Here is a description of the problem and solution.
WPML does not show proper language in WP-admin area. As soon as you switch language with the WP flag on top the language of the WPML menue and screens get messed up. I've seen all the other language or the other language mixed with English.
uncheck the option 'Set admin language as editing language.' from Users > Your profile page
This is the technical support forum for WPML - the multilingual WordPress plugin.
