Cannot optimize firewall | WordPress.org

Hello. I have modified the .user.iniand .htaccessfiles according to the documentation and the Firewall is still said to be only 35% set up and I am prompted to optimize it. I have verified with phpinfo() that auto_prepend_file is pointing to the correct wordfence-waf.php file and that the paths inside wordfence-waf.php are correct. I would appreciate any help, thanks!
