sorry I'm pretty noob with octane (even if I own a licence since first beta release

I'was trying to explore the material options , and I noticed that if you desactivate the reflexion channel for example , it doesn't take it into account , it keeps displaying the reflexion parameters . You need to first rise down the reflexion value to 0 then (but not needed so ) desactivate the reflexion chanel ..
(i didn't check but maybe it does the same problem with other nodes ? )
here a quick screen vid to show the problem
(I'm under C4D R15.064 / win7 )
