Group by year on created not working

I’m using CakePHP 3.4

I have to get visitors count group by YEAR from LogProfileVisits table.

What I’m doing is

$profile_visit_logs = $this->Users->LogProfileVisits->find()
   ->where(['user_id' => $user->id]);
$profile_visit_logs->select([
   'total_count' => $profile_visit_logs->func()->count('id'),
   'unique_count' => $profile_visit_logs->func()->count('DISTINCT `ip_address`'),
   'visit_date' => 'YEAR(created)'
])
->group('visit_date')
->limit(10);

But this is giving array of data according to date

object(App\Model\Entity\LogProfileVisit) {
	'total_count' => (int) 5,
	'unique_count' => (int) 2,
	'visit_date' => object(Cake\I18n\FrozenDate) {
		'time' => '2017-06-02T00:00:00+00:00',
		'timezone' => 'UTC',
		'fixedNowTime' => false
	}
}
object(App\Model\Entity\LogProfileVisit) {
	'total_count' => (int) 7,
	'unique_count' => (int) 3,
	'visit_date' => object(Cake\I18n\FrozenDate) {
		'time' => '2017-06-02T00:00:00+00:00',
		'timezone' => 'UTC',
		'fixedNowTime' => false
	}
}

Here, both visit_date is same ie., 2017-06-02 but count are different.
The counts should be total visits in a year and total unique ip addresses in a year.
