I often rate comics, but sometimes the ratings don't show up, not because of an error but because the code to show your ratings isn't there, they've been omitted or overlooked.

Check your comic, if your ratings don't show after the ratings buttons, consider editing your comic page layout (Webcomic Management > Edit Layout > Comic Page tab) to add this, scroll down and look for your ratings code lines, which start with something like:
<a href="[v:ratelink]&amp;vote=1" onclick='window.open

and beneath these lines insert:

<br>
average rating: [v:rating]
<br>
([v:votecount] votes)

Not obligatory, if you want to remain mysterious, keep things as they are!
