Discover failed

Hi, after fresh install CNSS Version  last Hot Fix 1 installed with last CND files for AP/STA 2.3 .  Clients with firmware 2.3  are not discovered. Clients with firmware 2.3.3 fail to determine type ... they are marked as Generic-1. What is wrong?

Thank for help


After deleting files CND Generic-1 and Generic-0 devices are labeled OK
