If it's any consolation OpenBabel stereo perception does not do CIP
ordering so any input that didn't have correct stereochemistry or it was
removed during whatever processing you did, its output InChi will have a
wrong stereo layer. I expect with properly doctored input you'll get
100% discrepancies there.
