Unit Frames options missing from Blizzards Interface Config

[HearthCore]

I've had this problem for a while, I wanted to disable the default Arena Frames in Arena (Since i use GladiusEx).. and never found the option while others clearly stated it was there, and obvious.

Now, after seeing a screenshot I've found that there are multiple Menu Entries missing on the left side.

This is for the German Local, if that does matter in any way.
I've uploaded the pictures, one with RealUI enabled, one without it enabled.




I hope you can either fix those options or integrate them in RealUI in the future.

Greetings
