This has been fixed on master.
[Solved] "There are no unread topics" appears even though there are unread topics
Self-explanatory from title, see screenshot below:
The "no unread" message should look like this in your
unread.tpl, if you've overridden the default template (from vanilla) in your theme:
<div id="category-no-topics" class="alert alert-warning <!-- IF topics.length -->hidden<!-- ENDIF topics.length -->"> <strong>[[unread:no_unread_topics]]</strong> </div>
If you haven't overridden it, then update vanilla
