VariantSet does not work


Good day to everyone, I’m trying to make a constructor based on this example (Product Configurator Template in Unreal Engine | Unreal Engine 5.0 Documentation /). The problem is the following, my options are implemented by the fact that in the blueprint of the product that I want to change, I create dynamic material and edit textures and material parameters with options, in the VariantSet editing mode everything works as it should, but when I press play, changing options and colors does not work.
