timebar persistence

I did ask this question earlier, however the response received did not solve the problem.

in the code below, when i use, "TimebarPersistence": "false", i still receive carried over values (i would not expect to see quotes on Saturday and Sunday). note: ticker1 is defined as "JPY="

requestUrl='https://selectapi.datascope.refinitiv.com/RestApi/v1/Extractions/ExtractRaw';

requestHeaders={"Prefer":"respond-async","Content-Type":"application/json","Authorization": "token " + token}

requestBody={
  "ExtractionRequest": {
    "@odata.type": "#DataScope.Select.Api.Extractions.ExtractionRequests.TickHistoryIntradaySummariesExtractionRequest",
    "ContentFieldNames": ["Close Ask","Close Bid","High Ask","High Bid","Low Ask","Low Bid","No. Asks","No. Bids",
      "Open Ask","Open Bid"],
    "IdentifierList": {
      "@odata.type": "#DataScope.Select.Api.Extractions.ExtractionRequests.InstrumentIdentifierList",  
      "InstrumentIdentifiers": [{"Identifier": ticker1,"IdentifierType": "Ric"},
                                #{"Identifier": ticker2,"IdentifierType": "Ric"}
                               ],
      "UseUserPreferencesForValidationOptions": "false"
    },    
    "Condition": {
      "MessageTimeStampIn": "GmtUtc",
      "ReportDateRangeType": "Range",
      "QueryStartDate":QueryStartDate ,
      "QueryEndDate": QueryEndDate,
      "SummaryInterval": "OneMinute",
      "TimebarPersistence": "false",
      "DisplaySourceRIC": "true"
    }
  }
}

r2 = requests.post(requestUrl, json=requestBody,headers=requestHeaders)

#Display the HTTP status of the response
#Initial response status (after approximately 30 seconds wait) is usually 202
status_code = r2.status_code
print ("HTTP status of the response: " + str(status_code))

if status_code == 200 :
    r2Json = json.loads(r2.text.encode('ascii', 'ignore'))
    jobId = r2Json["JobId"]
    print ('\njobId: ' + jobId + '\n')
    notes = r2Json["Notes"]
    print ('Extraction notes:\n' + notes[0])
