Noteheads not filled in- light gray

In the Score Editor of my Cubase 8.5 Pro, the notes are not filled in solid black, but are a feint barely visible gray and not very big.

I can’t seem to find where/how to fix this. Only instruction I saw in the docs was to click on one of the notes
and a notehead editor would appear. But I don’t see it.

What can I do to fix this ?
