You are not using a track matte, you are using the "Preserve transparency" switch:

Layer 6 will get its transparency from the composite of all layers beneath it, not just layer 7. Since you have only shown a sliver of your Ae UI, we can't see if there are other layers there that may be affecting your composite.

If you want to use a track matte, put the Shape Layer ABOVE your footage layer, then choose "Alpha Matte Shape Layer 1" from the TrkMat column.
