Hosts banned still have acces to my page

Hello,

Last week was the plugin changed into Ithemes security. And since then the banned hosts can still access my website.
Before it was working good.
I have enabled black list, banned users, banned hosts. Maybe I do something wrong.
And the feature to delete from logs all in once, I don´t like. It was very helpfull for me to delete only the logs I want to delete.

I´m thankfull for any answer.
Kindly Regards from Germany
