Copy Paste is pasting on multiple artboards.

I can't seem to find the answer anywhere. When working on a file with any amount of artboards, I can copy and paste and that image will show up on another artboard as well. So it's pasting in two places. Seems not to matter how far apart the artboards are. I have tried to install the last version and I'm still getting the same result. I figured they would have addressed it by now. Anyone have a clue as to what is going on?
