@TeacherJ ...

I see what you mean...that you are using the new "Enhanced Gradebook Filters" option for the Gradebook.  You're actually looking at the wrong spot, though...as displaying and not displaying unpublished assignments still exists.  Instead of clicking on the "Filters" button on the right side of your Gradebook, click on the cog wheel icon above it (just to the right of the "Import" and "Export" buttons.  Then, select the "View Options" tab from the fly-out menu that appears on your screen.  You'll see a checkbox for "Unpublished Assignments".  You can toggle it on/off.  Don't forget to click the "Apply Settings" button at the bottom of that fly-out menu when you're done.  Hope this helps!
