ray tracing issue with subsurface profile..

I’m wondering why subsurface profile material doesn’t work if I superimpose an asset that using subsurface profile material and an asset that raytracing translucent refraction.
It is shown as the result of applying the opacity value of the subsurface profile material as 0.
And, when the view mode is set to unlit, the subsurface profile is displayed in black, and the area where the ray tracing assets overlap shows the skin color as it is.

Raytracing translucency is a buggy mess atm.
