Module Search Plus ver. 1.7.2 not working

Hi,
after the last module update (1.7.2) even if a change the "search type" into "all words" (from module options) it always uses search type "any" on ajax search.
I don't use any template version of the module (no override from template folder)
If I inspect the page I can read "<input type="hidden" name="search_type" value="all"/>" but it's like if the value was "any".
