Yes we observed the same things, and we are working on this...

You could use R.E.D.-II
http://www.u-picardie.fr/labo/lbpd/RED/ to calculate
RESP charges for your 10 conf. or for each conf. taken individually...

There were similar questions about this topic in the AMBER mailing list. Do a
google search in the AMBER mailing list using 'RESP charge' & 'enantiomers'.
Enantiomers (and diasteroisomers) are not differentiate in LEaP (if they do
present the same atom/residue names).
