I suggested @KatieWoe make an issue for this, after she pointed out the discrepancy to me. I have no idea if any work is currently occurring or planned for this sim. No urgency from me, just wanting to have this noted for the next time there is work on the Mol Shapes pair of sims.

@emily-phet @KatieWoe thanks for pointing out. No work for this sim planned currently, will mark as deferred

Yup, sorry I didn't think of it like a month ago when it was being re-released.
