The "Parameters of host/service" page and ruleset lists showed an invalid match result for rules which value evaluates to None. For binary rulesets (the ones that only have yes/no as value) the result was also not displayed correctly.

The ruleset matching of Checkmk during checking was not affected by this issue.
