Getting a weird crop on png layers.

I have this png. When I double-click on it inside of AE, and view it in the Footage panel it looks exactly as it should.

However, the moment I drop it into a comp... I get this edge?

Zoomed in:

Literally didnt do anything to layer, but drop it into a comp. Didn't make it 3d.. didnt do anything.

Why is this happening?

I need this for a broadcast spot, and its happening on all 3 png layers that make up an animated gradient.

Set the Project to 16-bit. Check the Alpha Channel in the Comp Panel. If you add a solid below the PNG that is the same color as the center of the blue shape and set the blend mode to Difference, the hard edge on the alpha channel shows up.

Adding Channel Blur to the PNG layer and blurring the Alpha Channel about 40 pixels will solve the problem.

It seems you have underestimated selection feathering in Photoshop and clipped away some areas. Can easily be verified there as well, so it's not a specific AE issue contrary to my initial suspicion.
