I can’t see my footage in Fusion

I clicked a hollow square at the top of the screen in fusion and now, in every project not just that one, I can’t see my footage in fusion. Where the footage should be showing up, it’s just grey. Ive tried resetting my workspace and nothing happened. I’ve tried right clicking the median1 node (as well as Mediaout, and various transform nodes) and clicking View Left and View right. It works sometimes but other times it just stays grey. However if it does work, it won’t show any effects that I apply, just the raw footage. Anyone know how to fix this?
