Hi Boris,
I have seen this before and tried the exact same thing. Store:Set is not
thread set, and not supported by support. For example, do a full site
publish, when multiple pages are being generated by multiple page builder
threads, they are saving to the same variable for in Store:Set, so you will
have a race conditional, pages getting wrong information from previously
saved data.
I would say use this code below and leave the empty UL handling to CSS or
Jquery.
> <reddot:cms>
> <if>
> <query
> valuea="Context:CurrentPage.Elements.GetElement(opt_PageHidden).Value"
> operator="!=" valueb="hidden">
> <htmltext>
> <li>
> <a href="<%!! Context:CurrentIndex.GetUrl() !!%>"><%!!
> Escape:HtmlEncode(Context:CurrentIndex.Headline) !!%></a>
> </htmltext>
> <if>
> <query valuea="Context:CurrentIndex.HasChildren()"
> operator="==" valueb="Bool:True">
> <htmltext>
> <ul>
> <navigation:nextlevel>
> </ul>
> </htmltext>
> </query>
> </if>
> <htmltext>
> </li>
> </htmltext>
> </query>
> </if>
> </reddot:cms>

JQuery solution:
<script>
// remove all UL without LI inside
$('ul').not(':has(li)').remove();
</script>
