DA Comodo WAF plugin alert


I am using DirectAdmin Comodo plugin and I am getting this alert in cwaf → security engine :

“Custom Mod Security configuration found!
Press “Update config” button to update it with values from this screen.
After update, backup of current configuration could be found in: /etc/httpd/conf/extra/httpd-modsecurity.conf.custom”

This is my httpd-modsecurity.conf

LoadModule security2_module /usr/lib/apache/mod_security2.so

Why am I getting this alert ?

“After update, backup of current configuration could be found in: /etc/httpd/conf/extra/httpd-modsecurity.conf.custom”
I do update but I do not get any httpd-modsecurity.conf.custom file.
