Your thought made me wonder where it was set, but it is at 100%. I also wondered if maybe my controller might have an impact, but it is the same when unplugged. I did notice that when I 1st open a project after starting Platinum that default Screenset 1 looks normal. As soon as I change to different screenset and come back to #1 - it's got the problem on the midi channel.

Are those screensets made in Platinum or were they made in an older version?

They were made in Platinum, in a new project not imported.
Another odd thing. If I go to my PRV view (3), then back to screenset 1, screenset 1 looks perfect. If I go from any other screenset back to 1, 1 is messed up. No deal breaker, but just something that makes me wonder if it's just my system...
