using the PDB file shows you bonds based on distance. using the parm file
in VMD shows you bonds actually in Amber. that is the one you should look
at to understand what you are simulating.
It seems unlikely that leap would have put the H atom in the wrong
location. Is it possible that your loaded a pdb file into leap that already
included H atoms? If so, it could be an atom naming problem and it may be
best to remove the H atoms and let leap build them.
