Menu - Setup - Tuners & Scanning - Tuner configuration.
Then select your tuner en press Ok. One of the options near the bottom (if supported) should be "Force legacy signal stats", set this to Yes / green and see if that makes a difference.
If not, the driver doesn't support any statistics.
edit: ok, I see it's not supported.
I've added making a meta-driver package to my todo list, so it can be installed from the plugin / drivers screen next time.
