"Date" property exists in Object but returns "undefined"

So I'm using fast-csv to get all the rows from a csv file. The file I'm using is in UTF-16 format and using a ucs2 readStream, I'm getting every record out of the file.

_csv.fromStream(stream, {headers: true, delimiter: '\t'})
        .on("record", function(data) {
            count ++;
            console.log(data.Date);
            var dataHash = hash(data);
            if (!dict.hasOwnProperty(dataHash)) {
                dict[dataHash] = 1;
            } else {
                dict[dataHash]++;
            }
        })

I'm taking each row and I'm hashing it into a "|" delimited string. However, the date is not ever coming back correction. If I console.log(data), the Date property is definitely there but I cannot access it with data.Date, data["Date"], and data.hasOwnProperty("Date"); doesn't work either. The object looks like:

{
    'Date': '07/10/2014',
    '[Value 1]': 'xxx',
    '[Value 2]': 'xxx',
    '[Value 3]': 'xxx',
    '[Value 4]': 'xxx',
}

Has anyone seen this before and maybe know what I'm doing wrong?
