TOPIC: filtered items showing category as title

When I filter the hotspot list, each item in the list shows the category instead of title; I see that the code in default_hotspot.php is
<div class="hs-place-summary">
{{#if multimedia}}
<div class="hs-galleria"></div>
{{/if}}
<h3>{{ title }}</h3>
but I cannot figure out where the 'title' parameter is coming from; however, it is reading the wrong info

Why dont support fix this bug ?

I've just noticed that this is not true of all the hotspots, and those that it is true for have their alias field of the form /[number]-[category]., rather than [number]-[title]
I can't see why this should happen to some and not others...

Further testing shows that this is not the case; after filtering the hyperlink does read with the category, not the title, and this displays in the address bar; but reload the page without the filter and the address bar reads the correct link, so it is somehow caused by applying the filter
