I have a HIS on the N-ter and the pKa for the HIS sidechain is missing in the PROPKA3 output. I tested truncate the chain and make a intrachain HIS becomes the N-ter HIS. PROPKA3 give pKa for the former case and not the latter case.

Here are testing pdbs:

I believe this was fixed in v3.4.0 (Electrostatics/pdb2pqr#259)
