I have a problem when I want to change the data level, the problem is that the data level does not match the user ID

 public function updateLevel($level)
    {
        $checkuserToken = $this->users->where('level', $level)->first();
        if (count($checkuserToken) > 1) {
            if ($level == 'admin') {
                $data = [
                    'level' => 'superadmin',

                ];
                $activateUser = $this->users->update($checkuserToken, $data);
                if ($activateUser) {

                    return redirect()->to('/admin/admin');
                } else {
                    return redirect()->to('/admin/admin');
                }
                # code...
            } else {
                # code...
                $data = [
                    'level' => 'admin',

                ];
                $activateUser = $this->users->update($checkuserToken, $data);
                if ($activateUser) {
                    return redirect()->to('/admin/admin');
                } else {
                    return redirect()->to('/admin/admin');
                }
                # code...
            }
        } else {
            return redirect()->to('/admin/admin');
        }

this is my model

example
I want to change the data level with the user name tamaulanaa_
but that changes the data level with the user name udintod

what I expect is that if I change the data level it changes according to the user ID or username
