Why doesn't phpmd's own ruleset apply in phpstorm?

Question

PHP

Hello!
I need to be able to name private variables with an underscore at the beginning. I understand that the "CamelCasePropertyName" rule and its "allow-underscore" parameter are suitable for this.
Added rule to ruleset:

<rule ref="rulesets/controversial.xml/CamelCasePropertyName">
        <priority>1</priority>
        <properties>
            <property name="allow-underscore" value="true" />
        </properties>
    </rule>

Added it to PHPStorm in PHP Mess Detector valdidation. But variables with an underscore at the beginning are still underlined as errors.
Tell me what else can be checked, where to fix it?
//upd
I noticed that if I just run it with my own ruleset, then there are no errors.
phpmd ./components/View.php text ./build/phpmd.xml
If I add the controversial ruleset, I get an error

phpmd ./components/View.php text ./build/phpmd.xml,controversial
View.php:17    The property $_pageCategory is not named in camelCase.
