SXA autosuggest results sorting

Question

I'm using Sitecore 9.1 and SXA 1.8, this the configuration of the SXA suggester :

<searchComponent name="suggest" class="solr.SuggestComponent">
<lst name="suggester">
<str name="name">sxaSuggester</str>
<str name="lookupImpl">BlendedInfixLookupFactory</str>
<str name="dictionaryImpl">DocumentDictionaryFactory</str>
<str name="contextField">_language</str>
<str name="field">suggestionadge_s</str>
<str name="suggestAnalyzerFieldType">text_suggester</str>
<str name="payloadField">templatedisplaynameadge_s</str>
<str name="buildOnStartup">true</str>
<str name="buildOnCommit">false</str>
</lst>
</searchComponent>
<requestHandler name="/suggest" class="solr.SearchHandler" startup="lazy" >
<lst name="defaults">
<str name="suggest.dictionary">sxaSuggester</str>
<str name="suggest">true</str>
<str name="suggest.onlyMorePopular">true</str>
<str name="suggest.count">30</str>
<str name="suggest.collate">true</str>
</lst>
<arr name="components">
<str>suggest</str>
</arr>
</requestHandler>  

As I'm using BlendedInfixLookupFactory it should sort the results according to which item that has the searched query closer to the start of the suggestion.

But this is not the case as the below screenshot:

As the News Item 1 should be the first one.
