I said a DNN configuration issue, not an issue with DNN itself.
I can not reproduce this issue. I just tested using DNN 5.6.2 and AF 4.3.5 and a German language pack I got on DotNetNuke.com.
Can you give me more information about the process you used to localized the pages? Are you using a process similar to this:
