The minimum digital error of a balance is +/- 1 count so 500.0 +/- 0.1 difference is not unexpected. Also the difference between the "mass" and the "scale reading" is no more than 1 part in 5000 or 0.02%. I'm not sure your calibration weight is that good, or the linearity of the ADC in the scale is that good.
Neither is worth worrying about. You got a good scale for less than $10.

Any recommendations for a good and cheap scale? I'm looking for one that has a tolerance of .1g.
