Max Level Of Detail bug?

[C0R7E2]

Greetings, 

would like to kindly ask, that am I the only one, who can't enable this setting via the corresponding dropdown in Options, however the checkbox is "checked".
It was working fine till the last patch, after that i thought its only a minor thing to fix and hopefully this patch re-enables it. Well, it didn't. Any Idea, am i doing smthing wrong?

 

Have a great Weekend you all 0/
