This is weird. I'm not sure what you mean by "edit model", however. Is
"model" the name of some unit you have defined? What happens if you type
"edit unit" instead?
It may be that you have a non-standard PDB format, that VMD is somehow
interpreting correctly but LEaP is not. You might have to post the pdb
file. This doesn't seem like it has anything to do with the residue RES
definition: you can give LEaP a pdb file of completely unknown residues,
and it should still display it OK. You might try to break the pdb file into
pieces, and see what LEaP does with parts, in an attempt to debug the problem.

Where does nucgen fit in? Is your unspecified monomer a nucleotide?
