Adjustment Layer not working?

Hello. So I'm playing around with random effects here and I'm trying to make a moving scan that warps the image like an old VHS effect, right? So I make this adjustment layer (Scan) that is gonna run through the video. HOWEVER, it is ONLY working ontop of the Linear Light adjustment layer I made (with various coloring effects) but is also ( as you can see ) not even close to where it should be in my keyframes I set. I selected motion to show where it should be, but it's scanning way above that, and then the scan stops after the Linear Light adjustment layer ends. IF I delete my other adjustment layer, the scan doesn't show at all....I am so lost here, what is going on?
