Here are the menus I made:

FWIW, you probably shouldn't have to specify "German Forced" as an option here. If you choose German audio, the menu logic should auto-enable the German Forced subs--and the same thing for any audio language with corresponding forced subs. However, that does mean that any forced subs should be automatically disabled when you choose an audio track with a different language, and that logic might be more cumbersome. No idea, I don't do menus ;)
