Help: Solid layer from the Beam effect is showing up when I nest all the comps together

Apologies for this noob question.
Comp 1, I created a beam pattern from a solid layer starting from one end and finishing to another. After which I created a circle as the "ripple" effect from the beam.
Comp 2, I imported Comp 1, duplicated it into two instances and then offset with a rotation. However, the solid layer of the comps are showing up as a background. Such that it is covering the other Comps from showing through. How do I make the solid layers transparent so only these beams and circles from each comp show up and not be covered by the solid layer underneath?
TIA.
