Set Visibility on Commentary Box Blueprint

Hey there :)alt text
i migrated the commentary box from the “blueprintexamples”-project made available by epic and even after i changed up a few things it still works :wink: but i would like to set them invisible on start and set them visible if the key “5” is pressed… this works with every mesh i have in my level blueprint but the commentary box blueprints doesnt work (i have a few actor blueprints where i set the mesh itself in the blueprint on invisible but because the commentary box has this pulse effect i guess thats no option for me… :frowning: )

Error:

Level Blueprint:
