NAD M17 w/VM300 assing Composite video as a source issue

Christ! meant assign, not assing. I have not seen anything about this issue in the forum so I thought a post is in order. I have a NAD M17 with the Vm300 4k HDMI upgrade card. I cannot assign any composite or component video to a source. these to input types do not show up on front panel, OSD or in the iPhone app. the only option for source video is HDMI. what am I missing?

Thank you for any insight you may have.
