Are you basing everything you’re saying here on the first image you’ve captured for the lens calibration? The lens calibration uses up to 9 images to compute the distortion of the lens. After the first capture, you have exactly one sample, not nearly enough to compute the distortion, so the “un-warped” image you see will look completely bizarre, and this is normal.
The framework we use does appear to have weird issues on some versions of MacOS that behaves the way you’re describing, though I’ve not heard of it affecting the camera system before. Having said that, the visual feedback on the lens calibration isn’t really important - the score is really the only thing you need to pay attention to. If you get a good (low) score, you can move onto the next capture.
The most common issues with camera calibration (and solutions for them) are these:
