It's getting old doing this over and over.

I open an assembly and the floor reflection is on.  The only way I know to turn it off is to go into scene settings and uncheck the box.  Problem is I get a message that says I must use scene background to allow this, so when I hit okay, it changes my background to the scene background.  I don't want the scene background, I want my plain background, which is why I have selected plain background.  Why will the software not just allow me to turn off floor reflections  without having to take three steps by the time I go into options to change the background back to what I didn't want to change away from in the first place?

Or hopefully I am just missing something simple.  What am I missing here?
