Google Search Settings Not Saving Even After Reset

Hi. I've reset Safari (which also emptied the cache) but still the search settings for Google won't save, although Google says it had saved it. It keeps returning 10 results but I set and saved it to 100 results (it even confirmed that it was saved). When I set search setting again, it's back to 10 results. I'm using 10.6.5 and a late 2009 iMac i7. Thank you in advance.
