LEaP uses the connectivity information in the libraries to draw bonds, but
vmd and Swiss-PDB infer bonds from interatomic distances. Hence, if you have
bad contacts in your structure, the latter two programs draw these as bonds.
So once you fix the coordinate problem, the viewing problem will probably get
fixed as well.
