Import collection missing headers and body info

I have a Swagger 2.0 json generated file, which includes API calls that have headers for “wsc_api_key” and “wsc-acces-key”. Also, it has body parms for ull_stream_target with some pairs of name and values. None of these are showing up in Postman for the endpoint call. Here is a screen shot showing our data that is imported to Postman. The body in Postman says: “Provide the details of the ultra low latency stream target to create in the body of the request.” Would I see any different results if we were to build and use a “run it in postman button” rather than, import a file into a collection?
