It can't bring up a Dynamic Shadow as Masked made of translucent

Hi.
This is a bug found while making reference to the current material.

Usually, if you duplicate it with an instance material, you’ll bring all the settings.
I couldn’t bring the Dynamic Shadow as Masked setting.

So, as in the picture, the original material was well applied with shadows,
The instance material was not shadowed.

Just in case, I applied another option.
The options are working well in the instant material.

But, only dynamic shadows can’t be soaked.

Currently, the post process and light mass have already been applied to the level.

When using a normal mask, the opacity quality was reduced, so I found this bug while trying to use transparency.
