I downloaded your scene and change a few things.

Notice the correct alpha on the matte, the shadows are included.
Notice the correct blend on the RGBA.

Attached the scene, replace the hdri.

Use the latest Arnold build just released today and use ARV render view instead of using VFB+ The new drop includes grading tools.

Then keep the tick on.

The shadows are caught by the matte surface as seen here.

Works fine.
Remember to detick the Alpha Mask in the Matteshader.
