Cerber Black list too large to display on access list page. This is probably over kill.

Hello, I wanted to add a large known list of IPs to my blacklist. I downloaded from a git hub of blacklisted IPs. Once I have loaded all the IP's to the list, it no longer will display on the access list page. At some point after 100,000 it still adds to list, but does not display on page. List total is 188,276 IPs. Even though I can not see the list, does it still protect?
