Fortunately the description of Spirit Evidence is wrong and everything else should be fine. The Spirit Evidence is actually an undeveloped photo that Bruin Tram gave you, and Arjun Bhalla (not Bruin Tram) will need it at some point. In return Arjun will give you a developed photo ("photo of Bruin") to take back to Bruin.
At the same time Bruin gave you the Spirit Evidence, you would also have been given a quest saying that that Bruin needs the "photo of Bruin" from Arjun. This is talking about the developed photo, *not* the Spirit Evidence. So, just keep progressing down Arjun's storyline and eventually you'll be able to complete this short chain of events.
