I think (?) these are different rules, none of which have names, but this UI can clearly be improved.

I think the following change to src/applications/herald/controller/HeraldRuleController.php line 672 (as of 185c28f307e4) should provide an immediate improvement to at least indicate that they are different rules:

    foreach ($all_rules as $current_rule) {
      if ($current_rule->getIsDisabled()) {
        $current_rule->makeEphemeral();
-        $current_rule->setName($rule->getName().' '.pht('(Disabled)'));
+       $current_rule->setName($current_rule->getName().' '.pht('(Disabled)'));
      }
    }
