cubase 8.5 cant change sample rate !

cubase 8.5 is not changing sample rate on my AD/DA.
its not possible to change sample rate at project setup window!

am i the only person with this problem ?

i am using lynx aurora.
no such problem on 8, thats way i am still using 8.
trying to change on interface or project window doesnt help. i cant change it.
in project setting windows, sample rate turns “orange”
