[turba] Turba display not existing entries

[Piviul]

Hi all, I'm using turba to connect to an ldap public address book. On 
ldap I've created the address book and I have imported some ldif on it, 
added and deleted some entries more times from turba (just to do some 
trials) and now I have deleted all the ldap address book (and entries as 
well). If I try to browse it from turba I can find two entries that 
doesn't exist in ldap (the address book doesn't exist any more). If I 
create the address book in ldap and add entries these two entries still 
exist.

What I have to do to delete these not existing entries?

Thank you very much
