Trouble with Layers' visibility Frame animation

I am finding it hard to understand the visibility of layers in frame animation timeline. Let me explain.

I am illustrating on several layers in photoshop, while creating a frame animation timeline. Some of the layers have to appear in more than one frame. I have to move the illustrations in these layers around, so I'll go back and forth between frames in order to select. But as I select a specific frame, I noticed that when I look at the layers panel, the visibility toggles does not give an accurate reflection of which layers are on and off in a frame. Is this normal? It just seems like I should be able to see which layers are active in the selected frame.

When I want to move an object around in a layer, it moves around in all the frames it appear in, instead of moving in only the frame I selected. Do I have to duplicate the layer, and do the movement of each layer seperate? In other words it will leave me with more layers of the same object, but each layer placed differently.

Please help.

Thanks,

Danelle
