whitelist ip adres list ignored

it seems this list is ignored.

The IP is in the whitelist but still gets blacklisted when several times tried a incorrect login.
The user gets a message: your ip is blacklisted etc

When i tale a look it is indeed again added to the blacklist, when i open the whitelist the same IP is added/listed here aswell

I have thos problem on several servers with directadmin, it seems the blacklist overrules the witelist.
