Oputils Config File Manager SNMPv3 don`t work

Adding Cisco devices in Config File Manager with SNMPv3 don´t work for me. I have included the relevant mibs, configure the remote ip with the snmp engineid and creat a user for access. Everthing in the manual is done correctly but the Config File Manager will not work.

When I add the same device with the same snmpv3 credentials in the switchport mapper the devices will discovered corecctly. I have capture the packets which the Config File Manager send. There are 2 request with snmpv3 and then Oputils sends only snmpv2 packets with public domain. When I will add the device again Oputils continue sending snmpv2 messages until I restart the Service. Then there a again 2 snmpv3 request followed by snmpv2 messages.

I have try diffrent versions of Oputils till version 7. It´s always the same error.
