I cannot replace clip in Graphic templates

This is driving me insane. It feels like it should be the easiest thing to me.

I open the graphics template window and choose the Classic Logo Presents template. I drag this into the timeline, and select it. This opens some settings in the property menu. I can see all of the layers the template has, and I can change some settings. I am able to change text by double clicking in the program monitor.

But I am unable to figure out where to change the Clip/Media/image. I can hide/show it. I can duplicate it. I can add more layers. But I cannot for the life of me figure out where I can simply replace this placeholder media. Please help this idiot.

Thank you in advance!
