Masking doesn't work on multiple objects?

I don’t know what I’m doing wrong here, I’m doing it the same way as I did my first animation but now - masking won’t work over multiple object?

This is how I’ve done it.

  • opened new scene
  • made 2 layers, one for image, second for masking effects
  • on that masking effect layer - i drew 2 rectangles
  • control + g to group
  • F8 and converted to Movie clip
  • double click on the movie clip
  • create another layer for light
  • masked the first layer

And now - only the first rectangle gets the effect right… ??
