[USG Flex 200HP] - SNMPv3 User without Privacy

Hello everyone,

I've configured an SNMPv3 User without enable the Privacy Encryption:

When I save the configuration, into the User Configuration table is present the user but seems have the Privacy Encryption set:

I use the SNMPWalk utils, and this is the output:

SNMPWalk with Privacy (as the table describe), going in timeout, otherwise if I use SNMPWalk without Privacy, I obtain the reading.
