Nodejs headers not matching actual request

There is a problem with NodeJS v7.9.0 where there can be a request

curl -i -H Accept:application/json -H range:bytes=1-8 -X GET http://localhost:8080/examples/text.txt

However node's request header doesn't match when it is logged

console.log(req.headers.range)

The logged value varies between different values for the exact same request (some values logged from that request: bytes=1-2, bytes=1-3, bytes=1-4, bytes=1-5, bytes=1-6, bytes=1, 7 bytes=1-8)

Is this a problem with NodeJS or something else with the computer's setup? And how does one fix it

Note the requests are being made with "Rest Web service client" (chrome plugin), and the request above is the equivalent curl command.
