Issue filtering specific logs on UF

[tirthasplunk]

Hi,

I have recently started building apps on splunk. I am monitoring a log file on the UF , containing logs from various applications and trying to fetch specific alert logs from a containing "VERITAS-COMMAND-CENTRAL-MIB". Below are the files I have configured for the the requirement. Issue is, the logs are getting tagged to a different source type(snmptrapd) instead of the intended one (st_netbackup) . Both my enterprise and UF are on 7.1.4 version.

inputs.conf

[monitor:///var/log/snmptrapd.log]
disabled = 0
index = acn_backup_netbackup_tier1_idx

index = main

host = XX.XX.XX.XX

System level outputs.con

[tcpout:acn-dev1-route-group]
server = xx.xx.xx.xx:9997

props.conf

[source::/var/log/snmptrapd.log]
description = Netbackup log file
TRANSFORMS-set = removeNETSNMPHeader,removeOther
TRANSFORMS-route = parseNetbackup
SEDCMD-community = s/community (\w+)/community *****/g
BREAK_ONLY_BEFORE = \d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}
TIME_FORMAT = %Y-%m-%d %T
TRANSFORMS-customsourcetype = st_netbackup

transforms.conf

[st_netbackup]
REGEX = (!?)VERITAS-COMMAND-CENTRAL-MIB
DEST_KEY = MetaData:Sourcetype
FORMAT = st_netbackup

[removeNETSNMPHeader]
REGEX =NET-SNMP version*
DEST_KEY = queue
FORMAT = nullQueue

[removeOther]
REGEX = (.)
DEST_KEY = queue
FORMAT = nullQueue

[parseNetbackup]
REGEX = (!?)VERITAS-COMMAND-CENTRAL-MIB
DEST_KEY = _TCP_ROUTING
FORMAT = acn-dev1-route-group

Below is the log format as received on the desired index. It would be great to hear any suggestions here.
