Why can I not create a collection with no owner in the Lookup File Editor App for Splunk Enterprise?

I just got the Lookup Editor app and I created a test kvstore lookup (or rather a collection since this app doesn't actually create lookups) and there was no option to have the owner be nobody. After I created the test collection, I immediately started putting in test data which all worked fine. The problem I have is that when I selected my collection in the interface, it brought up data "Showing all entries for: [my_user]" but the data itself was up in under user: "nobody". Why is this? Can we just set the owner to either our logged in user or nobody? Did I miss that option and why did it put in the data under the user nobody and not my personal user? I am running Splunk Enterprise 6.4 and I just downloaded the Lookup Editor App today. Any help would be appreciated.
