Widget not Showing

I am trying to use one of the music player widgets, on the preview in the app it displays the music name/artist/cover ect. As it should, however when I exit the advanced editor it just displays an empty white box. Whats the problem with this?

This is pretty weird, did you save? If you just installed KWGT i would suggest rebooting once your device just to be sure there are no issues with the Music interface. Also ensure you started your player at least once and that you are running latest release (3.23 at the time of writing)
