Sometimes Magento admins face the issue of some values missing from the frontend even though the configuration would have shown to be saved from Backend. This could be due the limit in the Magento Suhosin value.
The common override for this issue is to have the following values set in .htaccess
php_value suhosin.mail.protect 0
php_value suhosin.memory_limit 128M
php_value suhosin.post.max_vars 5000
php_value suhosin.post.max_value_length 500000
php_value suhosin.request.max_vars 5000
php_value suhosin.request.max_value_length 500000
php_flag suhosin.session.cryptua off
For php.ini use the variables without php_value or php_flag
