Can't add insert effects? HELP

Right in the middle of my Cubase 10 project all of a sudden I can’t add insert effects anymore. The insert effects that were already in place are like grayed out and now I can’t open them. Any idea how this happened and how I can fix it without losing this project? Cubase 10 with latest update 2/20. Cubase for mac. Mac oS 10.14.6

here’s screenshot of this madness. It’s happening on ALL channels

cbase

At the bottom of the inserts section, there are two buttons. You have accidentally clicked on Routing. You need to click Inserts.

Thank you for your help!
