samba - Feb 2021 - vfs full_audit %m and %M variables return IP address

Hey all, I have the full_audit plugin configured on a Samba AD domain member
acting as a file server. My issue is that when adding the %m (NetBIOS name) or
%M (DNS name) variables in the full_audit:prefix line, they both return the IP
addresses of the connected computers, even though they are all domain-joined
computers. Is there a way to correct this??
Here's the smb.conf:?
[global]? workgroup = AD? security = ads? realm = AD.EXAMPLE.COM
? log file = /var/log/samba/%m.log? log level = 1
? idmap config * : backend = tdb? idmap config * : range = 3000-7999? idmap
config AD : backend = rid? idmap config AD : range = 10000 - 999999
? winbind use default domain = true? winbind offline logon = false? winbind
refresh tickets = yes
? vfs objects = acl_xattr, full_audit? map acl inherit = Yes
? template homedir = /home/%D/%U? template shell = /bin/bash
? username map = /etc/samba/user.map
? disable netbios = yes? smb ports = 445
? full_audit:prefix = %u|%I|%m|%S? full_audit:failure = connect?
full_audit:success = open mkdir rmdir pwrite rename unlink? full_audit:facility
= local5? full_audit:priority = notice
Thank you.
