Note: Even in SAM mode (and pressing the Zero Beat button) you may still see this carrier in the spectrum.

What you are seeing is the AM station carrier beating against the SDR (just like an analog receiver with the bfo on). If you switch the SDR to SAM mode it will sync the SDR and the carrier and you will have great sounding AM.
