Parts of decal only showing on characters, not pawns

Hello

I`ve come across a strange problem today. I am creating dynamic ice spreading and the decals are appearing on pawns and characters.

When I use a character as the player character, all textures in the decal material are appearing on screen.
When I use a pawn as the player character, only parts of the decal material are appearing on screen.

Now my question: Do pawns and characters normally show decals differently? Or is this a bug?

Decal blend mode: Translucent

Character:

Pawn:
