I can reproduce this on the Sense App as well as from my.innuos.com in the browser:
From Music -> Tags -> click on any tag
-> from drop down next to Album, pick either All Artists or Album Artists or Composers;
See list of artist names and their circular icons;
-> click on any artist
See albums of that artist;
-> click on the back button ('<') on the top left corner.
This brings back to the list of artists, except that the circular icons are all blank and the spacing between them is squished so that the artist names are no longer invisible.
