Please Help 301 redirect

I have problem with redirect in htaccess from http://www.corink.ie to http://corink.ie
I cant find where is problem...

on google search result is http://www.corink.ie
when i go to shop from www i get adres http://www.corink.ie
when i go to shop corink.ie i get adres corink.ie

I think that htaccess should redirect all www-> to non www even if i write www

On webtools I set prefered domain to corink.ie

my htaccess is
