DA Comodo WAF plugin alert

Hi,

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

LoadFile /usr/local/lib/libxml2.so
LoadModule security2_module /usr/lib/apache/mod_security2.so

# Default recommended configuration

# ModSecurity Core Rules Set and Local configuration

IncludeOptional /etc/modsecurity.d/*.conf

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.

Thanks
