Bug: Undefined index

With Query Monitor I can see the following PHP Notice:

Undefined index: buttons
wp-content/plugins/woocommerce-checkout-manager/includes/class-wooccm-compatibility.php:418

The code is the following:

      // Additional compatibility with 4.x
      // ---------------------------------------------------------------------
      if ('wccs_settings' == $name) {
        $fields = (array) @$fields['buttons'];
      }

Adding an “array_key_exists” as it’s done in the previous lines would solve the problem.
