Well, which version of Silent Hunter 4 are you using? The most common one years ago was v1.3, then 1.4 and then 1.5, also known as Uboat Missions Addon, and later Gold Edition. If you have a choice for a German Uboat career, then you have v1.5. Also, do you have any mods enabled? If you do, then what folder do you have SH4 installed in?
