Game difficulty

Hello !

I have some problem with the game difficulty.
In options I can chage whether I want to have limited fuel or not - bot it doesnt work, when it comes to the game start, where I choose game difficulty with the date of start and renown.

I can use limited fuel in options, but when I choose normal game the fuel is unlimited ...
Does anybody knows how to fix it ? Because I want limited fuel and automatic targeting for torps. In normal I have none of them, but in hard I have both - I just want to have limited fuel.
Its like this:

Choosing difficulty in menu with start date and renown

NORMAL: limited fuel OFF
manual targeting OFF

HARD: limited fuel ON
manual targeting ON ( how can I change that to automatic???)

PS. Im using U boat addon with OM and speech fix.
