This seems to happen on many pages, but for an example go to:
http://www.taulia.com/resources/whitepaper-downloads.html
Then go to the German translation by adding the "/de" like so:
http://www.taulia.com/de/resources/whitepaper-downloads.html
Then click on the American flag in the top right.
The page returns to English, but if you rollover the menu links on the left (or dropdowns on the top) you can see they will take you to German pages.
How can I fix this?
Thanks.
