Ah, I (o1 pro) can see a difference in your Blueprint and mine. There must just be one SoundWaves object that is connected to all the objects that use it. So you just create one variable called SoundWaves and connected it to the different Sound connectors.
I actually pasted the two Blueprint images into o1 pro and it gave me this pointer, but also made up a couple of problems that might not not be there.
