Route error when the value is greater than 9

My configuration:

Code:

$routes->group('members', ['namespace' => 'App\Controllers'], function ($routes) {
    $routes->get('/', 'Members::index');
    $routes->add('(:any).(:num)/aaa', 'Members::aaa/$1.$2');
});

My link: https://domain.com/members/abcdef.13/aaa
When "(:num)" is less than 10, it's true.
When "(:num)" is greater than or equal to 10, it's false.

I'm on my phone commuting so I'm just guessing: I think the route function should be defined as Members::aaa/$1/$2 so you pass the (:num) segments as two arguments properly.

This is function in Controller:

Code:

public function aaa($slug = '')
{
    /* I will get slug = (:any).(:num)
}

I'll get value (:any).(:num).

Add a backslash before the dot between (:any) and (:num)
(:any)\.(:num)

Add a backslash before the dot between (:any) and (:num)
(:any)\.(:num)

Thanks @iRedds !
It's work!
