Windows UWP App not showing username

[LoneLycanroc22]

I have Spotify Premium, and I'm using the Win10 UWP app on a Dell StudioXPS, and for some reason, my display name, or user name [The Lone Lycanroc] won't show on the app at all. Instead, it shows some generic string of code I don't even understand, and doesn't even show my picture. Not only that, if I go into the settings, hoping that it will show it there, it DOESN'T! It still shows the same darn string of letters and numbers which have no dang sequence, and of course, no picture. I didn't have this issue at all on a virtual machine running Windows 7, so I'm assuiming it has something to do with the UWP and not the regular program. This is starting to really frustate me. Anyone have any advice?
