Incorrect redirect in AdWords .htaccess gclid

I'm having a problem with the AdWords ad, when a person clicks on the advertiser it should be redirected to the homepage, but then it is redirected to another search page, with the following url: link

The .htaccess file looks like this:

Options All -Indexes
RewriteEngine on

RewriteBase /

RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{REQUEST_URI} !(/retorno_payu\.php|/retorno_payu_assinaturas\.php[^.]*)$ [NC] 
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php?$1 [QSA]
