Research direction
Reproduce the reported structures in Ketcher micromolecules mode using the linked images, then run Calculate CIP before and after copy/paste. Compare the assigned stereo-labels with the expected E labels in the first row and Z labels in the second row; the issue does not identify a source file or test.
