My animated keyframes aren't showing in the effects panel. How do I make them reappear?

Hi All, I animated some .png files on my timeline using the effects panel. I adjusted the position, added a crop layer and a mask to animate it. Everything went fine but now when I go back to adjust the keyframes and smoothen the transitions, the keyframes aren't there. The .pngs are still animated but the keyframes are missing and there's no button that says "show keyframes" in the effects panel.

It's really strange because the V2 layer in screenshot 1 has keyframes but the other layers don't so I can really use some help with this one. Thank you so much!
