Hard to tell from the screenshots, but at least: do not add the two Principled Shaders. Use only one Principled Shader !
Mix the two Roughnesses (I don’t know if you need to Multiply, or Add, or… them) and use something to decide on the Metalness factor (again, don’t know what exactly you want to use there…)
I know it’s vague, but I hope it helps;)
