Some IPs encrypted in Blacklist, some not?

Hi Folks,

Just curious as I'm a new user of the AVH First Defense Against SPAM pack.

It's a great plugin package..thanks. It appears to be working really well. However, I'm curious about the Blacklist.

The IP Blacklist is in the 'General Options' section. When I first installed the package (a bit over a week ago), it appeared to be encrypting all the IP Addresses that I blacklisted. Then it suddenly stopped doing this and just showed the IP Address (see the attached Screenshot). So now it has both...is this how it should be working?

Thanks in advance for your assistance.

Cheers

Stephen G
