Interesting Vincent. Is it possible you don't have rules with a zero hit count? This is tested on 80.10.
I'm going to have you run the raw command to look for the output;
mgmt_cli -r true show access-rulebase name "************-FW-POLICY Network" details-level "standard" use-object-dictionary true show-hits true --format json | jq --raw-output '.rulebase[] | select(.hits.value == 0)'
See what that outputs. If it's nothing then run this;
mgmt_cli -r true show access-rulebase name "************-FW-POLICY Network" details-level "standard" use-object-dictionary true show-hits true --format json | jq --raw-output '.rulebase[]'
Then look for the output of each rule and the hits value; which should look like the below (I formatted the text you would look for)
