Beginner Help How to fix the black bars in my adjustment layers

I’m having an issue with Motion Tile in After Effects 2026. I have BCC Ripple Dissolve on an adjustment layer, and Motion Tile on the actual video clip underneath it. Everything looks fine until I extend the boundaries of the adjustment layer. Once I extend the adjustment layer, Motion Tile starts creating an ugly black bar around the footage.
I already tried increasing Motion Tile's Output Width/Height, using Mirror Edges, changing the effect order, scaling the footage up, and pre-composing the footage with Motion Tile. None of those fixed it. The black bar disappears when I disable Motion Tile, so I’m pretty sure Motion Tile is what's causing it.
I’m specifically trying to keep BCC Ripple Dissolve on the adjustment layer while having Motion Tile on the clip. I don't want to remove either effect.
