Custom Texture in a Material from Editor

Hello, today i found an issues but still dont know if its my fault or something wrong with UEFN.

This is my material setup ( easy one with a texture parameter QuizImage

the texture i have assigned like this:

quiz_texture := class<concrete>():

    @editable
    CorrectTexture : texture = Textures.Quiz.T_quiz_default

    @editable
    IncorrectTexture : texture = Textures.Quiz.T_quiz_default
CorrectMaterial := Materials.M_Quiz_material{}
IncorrectMaterial := Materials.M_Quiz_material{}

set CorrectMaterial.QuizImage = QuizTexture.CorrectTexture
set IncorrectMaterial.QuizImage = QuizTexture.IncorrectTexture
                
Level.RightSide.SetMaterial(CorrectMaterial)
Level.LeftSide.SetMaterial(IncorrectMaterial)

The problem is with the new material, its not getting the texture wich was defined in the editor, it only gets the default texture i have assigned, looks like the editable is not working for new material generation

I am doing something wrong or this is a uefn issue?
