I found the following part in the template. Do you see any problem there?
<!-- The following CSS hides visual elements of the progress bar from screen readers. -->
<style type="text/css" media="aural tty">
progress-graph .zero, progress-graph .graph, progress-graph .cent { display: none; }
</style>
I cannot support LimeService users. But you should change your template to a default one to see if you still have problems. You can export your customized template and upload it here.
I think this is normal. There is 0% to the left of the bar and there is 100% to the right of the bar. I think I have never seen that it writes the actual percentage...
