Can you provide more specific information? Are some residues mapped and not
others? What is in the pdb file itself for the residue name? And what does
it become inside leap (I assume you are using loadPdb?)

Try the dna version (leaprc.ff99): does that map things do DNA with your
input files? A little bit of sleuthing may help to narrow down the problem.
My best guess from the above is that the residue in your pdb file don't match
anything that leap expects to know about, so be sure to give an (small)
example file that fails to work....
