It looks like you are using protonate to convert an Amber pdb file back
towards Brookhaven-like nomenclature. I can confirm your problem with
Amber 7. Looks like this was only fixed in going to Amber 8. If the rest
looks OK, you could put the mystery protons (and other atoms) back in the
output by hand (as a workaround).
The protonate program was extensively reworked a couple of years ago, and it's
not easy to see how to simply patch version 7 to fix this problem.
