API contact edit method is not working

Something strange happening on Mautic version 3.3.3 and API version 3.0
Edit a contact method is not working. I have this

$data  = array(
                                'cancellation_date' =>date('Y-m-d'),
		               'acc_cancelled_flag' => 1
		);
		$initAuth = new ApiAuth();
		$auth = $initAuth->newAuth(mauticConnection(), 'BasicAuth');
		$timeout = 10;
		$auth->setCurlTimeout($timeout);
		$api = new MauticApi();
		$contactApi = $api->newApi("contacts", $auth, checkMauticUrl());
		/*Get User*/
		$contacts = $contactApi->getList("email:$email");
		//dd($contacts);
		if (!empty($contacts['contacts'])) {

			$user_id = array_key_first($contacts['contacts']);
			/*Update User Details*/
			$response = $contactApi->edit($user_id, $data, false);

		}

This is the method that I am using but its not udpating those two columns. Does somebody has solution?

Start by reproducing the provided Mautic API 3.0 contactApi->edit call against Mautic 3.3.3, using the two fields shown in the request. Inspect the contact edit path and determine why those fields are not updated. Done means the API persists both values and the behavior is covered by a regression check.
