ERROR/warning when read pdb files

I want to know whether the following ERROR/warning matters when I mutate amino acids in pyrosetta:

core.import_pose.import_pose: File '/data2/rjli/test_dataset/1amk/1amk_protein.pdb' automatically determined to be of type PDB
core.io.pdb.HeaderInformation: [ WARNING ] Deposition day not in range [1, 31]: 0
core.io.pdb.HeaderInformation: [ WARNING ] Unrecognized month in HEADER deposition date             
core.io.pdb.HeaderInformation: [ ERROR ] Malformed Compound record found: ' 1AMK_PROTEIN'
core.io.pose_from_sfr.PoseFromSFRBuilder: [ WARNING ] discarding 4 atoms at position 1 in file /data2/rjli/test_dataset/1amk/1amk_protein.pdb. Best match rsd_type:  SER:NtermProteinFull

THE PYTHON CODE :

import os
from pyrosetta import *
from pyrosetta.rosetta.protocols.simple_moves import MutateResidue
init()

source_folder = '/data2/rjli/test_dataset'

for id in os.listdir(source_folder):
    folder_path = os.path.join(source_folder, id)
    if os.path.isdir(folder_path):
        for file in os.listdir(folder_path):
            if file.endswith('protein.pdb'):
                protein_file = os.path.join(folder_path, file)
                pose = pose_from_pdb(protein_file)
                n_res = pose.total_residue()
                # loop over all residues
                for i in range(1, n_res + 1):
                    res = pose.residue(i)
                    if res.name() == "ASN":
                        # create a MutateResidue mover to mutate Asn to Leu
                        mut = MutateResidue(i, "LEU")
                        mut.apply(pose)
                    if res.name() == "GLN":
                        # create a MutateResidue mover to mutate GLN to Leu
                        mut = MutateResidue(i, "LEU")
                        mut.apply(pose)
                output_file = os.path.join(folder_path, f'{id}_mutate0_protein.pdb')
                pose.dump_pdb(output_file)

Start with the supplied Python loop and its pose_from_pdb call, then inspect the input PDB header and compound records alongside the reported discarded atoms. Determine whether the warnings change the loaded pose or the subsequent mutations; the issue is done when the impact of each message and any required input correction are documented.
