Material Functions are incorrectly listed in the Layer Asset list

Since UE 5.7, Material Functions are included in the Layer Asset list of the Material Layers of an instanced material using material layers.

It is also possible to drag and drop Material Functions into the list.

• Prepare a material that uses Material Layers.

• Create a material instance from the material.

• Check the Layer Asset list under the Material Layers in the instance's Layer Parameters panel
