Device Port Out doesn't work Cubase 8 Pro and Roland 1610

Hello,

I use Cubase and Roland UA 1610. I have 10 output devices on this souncard . I can send the sound output only with 1-2 on a current project. I have no sound on the output 3 or 4 per exemple.But on the same project it was ok before upgrade Cubase Artist to Cubase Pro.Or when I start a new project , it works.
