Static Mesh not showing up

I have for the past week tried to do a Gardenscape kinda feature where the player can go over and pick between 3 different choices of customizations to their level. Its been a nightmare to be mild.

Please just someone explain to me why this simple simple simple code is not working. All i want to do is being able to show different meshes so I can duplicate the blueprint around and give it different meshes but its just ■■■■■■■ me up badly.

As always. If you, Epic, are reading these, please let us write on this forum withtout this insanity of uploading one file at a time and no copy pasting of snippings. It takes ages making a post for the single reason you sit and have to manually drop one in at a time.
