Problem: Grade only Visible in Highlight Mode or Split View

DR15
MBP Retina 2015
High Sierra 10.13.6

My color grade is only visible in Highlight Mode or in Split Screen mode.
My nodes are -- Shot Match --> Primary Wheels / Curves

I've checked and double checked that I don't have any masks on.

Cannot figure this one out -- bug -- or d'oh?

Thanks for any help.

Solved?

I removed all attributes from the clip in the Edit Page and then the grading appeared.

I then Command Z'ed (undid) and then went to the inspector and toggled off each option one by one.

The grading appeared when I toggled off the Composite switch... even though I was in Normal Composite mode.

Posting in case anyone knows why this would be the case or if anyone else runs into this.
