Refinitv Tick History Historical Search for Chain RIC

Chain RIC 0#SIRT- gives incorrect end date (2017-05-06) using 'ResultsBy': 'Entity, however without 'ResultsBy': 'Entity it gives correct end date:

with 'ResultsBy': 'Entity

when sending request
@{'Request': {'@odata.context': 'http://selectapi.datascope.refinitiv.com:83/RestApi.Help/$metadata#DataScope.Select.Api.Search.HistoricalSearchRequest',
'IdentifierType': 'ChainRIC',
'Identifier': '0#SIRT-:',

'ResultsBy': 'Entity'}}
to below
https://selectapi.datascope.refinitiv.com/RestApi/v1/Search/HistoricalSearch

it returns

Also, why does the 1st API response shows 0#SIRT-: as RIC
And the chain0#SIRT-: is active till date(why doesnt end date shows as todays date)
