$value coming as document header in browser while opening file sent via odata in UI5 application

I am trying to fetch documents from backend SAP through ODATA service and display them in my Fiori application. Everything works fine except that the document title is showing as $value( taken from the URL that it's hitting ) in Chrome browser. Downloading is working fine and I am getting the correct filename there. Any idea how to correct the document title in the browser as well?
