I tested on fresh new 21.x install but no rules appear. I enabled VueJS and the Tracker Rules feature as instructed on http://doc.tiki.org/Tracker-Field-Rules
In Chrome Google console I just get:
Failed to load resource: the server responded with a status of 404 (Not Found)
/tiki21x/temp/public/vue_TrackerRules.js:1
Same result on dev.tiki.org
