Have you run the Calibration routine yet? (If not, the link is here.)
After calibrating, you’ll want to use the Set Focus tool, particularly at the edges of the bed, to adjust the camera view to account for the fisheye distortion in the lid camera. (Also described at that link above.)
Not sure what caused the misalignment on the second pass…if you left the material untouched in the bed and didn’t shift the design on the screen it should have landed in exactly the same place when you hit Print the second time. If the material got nudged or bumped when you were checking it, then it would land in a different place though, so we like to use Honeycomb Pins to pin the material down before starting a print. (Makes sure it stays put.)
