Power ports are a "special" type of item. you could prob best think of them as an invisible track that automatically connects itself together. so any power ports of the same type will automatically connect together.
They are not real components so they are not annotated. why are you creating a power port like component? You either create a component or you create a power port. You can't mix the two.
