Intraday extraction does not return data for FX instruments

We are using, in our TRTH migration process, the following endpoint and report template for retrieving intraday data:

/Extractions/TickHistoryIntradaySummariesReportTemplates

{
    "@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ReportTemplates.TickHistoryIntradaySummariesReportTemplate",
    "ShowColumnHeaders": false,
    "Name": "12456790_REQUESTINTRADAY_TPLT_20170919.114535.380",
    "Headers": [],
    "Trailers": [],
    "ContentFields": [{
        "Format": null,
        "FieldName": "Open"
    },
    {
        "Format": null,
        "FieldName": "High"
    },
    {
        "Format": null,
        "FieldName": "Low"
    },
    {
        "Format": null,
        "FieldName": "Last"
    },
    {
        "Format": null,
        "FieldName": "Volume"
    }],
    "Condition": {
        "MessageTimeStampIn": "LocalExchangeTime",
        "ReportDateRangeType": "Range",
        "QueryStartDate": "2017-09-14T00:00:00.000Z",
        "QueryEndDate": "2017-09-14T23:59:59.000Z",
        "DisplaySourceRIC": false,
        "SummaryInterval": "FiveMinutes"
    }
}

The instrument list is populated with several types of instruments. An example of that is shown below:

{
    "Identifiers": [{
        "IdentifierType": "Ric",
        "Identifier": "SAN.MC"
    },
    ...
    {
        "IdentifierType": "Ric",
        "Identifier": "EUR="
    },
    {
        "IdentifierType": "Ric",
        "Identifier": "EUR10MV="
    }
    ... 	
    ],
    "KeepDuplicates": false
}

Taking into account only the three instruments above, the extraction file only contains intraday data for the equity (SAN.MC)

SAN.MC,Market Price,2017-09-14T09:00:00.000000000+02,Intraday 5Min,5.58,5.585,5.57,5.581,390775

The extraction provide us no data for FX instruments (EUR=,EUR10MV=)

Any idea about what's happening?

Thanks
