Why splunk Search returning duplicates?

[karthi25]

As shown below I have only two events present on my index

But when i execute the below search query

index = **** |rex field=_raw "(?msi)(?<json_field>\{.+\}$)" | spath input=json_field |rename SCMSplunkLog.SCMFailureLog.appName as APPNAME,SCMSplunkLog.SCMFailureLog.eventType as EVENTTYPE,SCMSplunkLog.SCMFailureLog.payload.level as LEVEL,SCMSplunkLog.SCMFailureLog.payload.errorDescription as ERRORDESCRIPTION,SCMSplunkLog.SCMFailureLog.payload.startTime as STARTDATE,SCMSplunkLog.SCMFailureLog.payload.endTime as ENDDATE |where APPNAME!="" and LEVEL="ERROR"|table APPNAME,EVENTTYPE,STARTDATE,ENDDATE,LEVEL,ERRORDESCRIPTION

I was getting duplicate entries on result table as below

Can anyone please help me with this.

Edited:
Attached sample json:

{
  "SCMSplunkLog" : {
    "SCMFailureLog" : {
      "appName" : "Testing_splunk_alerts_log",
      "eventType" : "Testing_splunk_alerts_log",
      "payload" : {
        "level" : "ERROR",
        "startTime" : "2022-04-12T13:57:49.156Z",
        "successCount" : 0,
        "failureCount" : 0,
        "publishedCount" : 0,
        "errorCode" : 0,
        "errorDescription" : "ERROR: relation \"test.testLand\" does not exist\n  Position: 8",
        "sourceCount" : 0,
        "endTime" : "2022-04-12T13:57:54.483Z"

I tried the same that you have. It seems working as expected.

| makeresults | eval _raw="{
  \"SCMSplunkLog\" : {
    \"SCMFailureLog\" : {
      \"appName\" : \"Testing_splunk_alerts_log\",
      \"eventType\" : \"Testing_splunk_alerts_log\",
      \"payload\" : {
        \"level\" : \"ERROR\",
        \"startTime\" : \"2022-04-12T13:57:49.156Z\",
        \"successCount\" : 0,
        \"failureCount\" : 0,
        \"publishedCount\" : 0,
        \"errorCode\" : 0,
        \"errorDescription\" : \"ERROR: relation \"test.testLand\" does not exist\n  Position: 8\",
        \"sourceCount\" : 0,
        \"endTime\" : \"2022-04-12T13:57:54.483Z\"
      }
    }
  }
}"
