Lines added to SOAP PDF Request

I have a request that I normally use within SOAP UI, but need to move it into Postman. The PDF downloaded from the SOAP UI is fine, but Postman seems to add additional information in the response. Everything before the %PDF-1.6 only appears in the Postman response, and not in the SOAP UI response. Unfortunately, the addition of these 12 lines results in the PDF being corrupt.

I honestly have no idea how to get around this and am hoping someone has seen this type of behavior before.
