Axis can change, but your astigmatixm isn't going to amount to much.
The amount of astigmatism (Cyl) at axis 56 (+0.25D) and 175 (+0.25D) is fairly negligible as is the lack of astigmatism is 2013 for the OD (right eye).
OS is a different story: you went from -1.00D to +1.00D which amount to a 2D magnitude difference...that's huge; the axis didn't change much, but the magnitude did. I would go in and get this checked for an error.
