Using get_terms function in MB Views (Twig). The result is not as expected

I’m using MB Views to create a shortcode that lists my custom taxonomy. In my Twig template, I use the get_the_terms function like this:

{% set cats = mb.get_terms({ 'taxonomy': 'wd_portfolio_cat', 'hide_empty': false }) %}
{{ mb.var_dump(cats) }}

However, the output I get looks like this:

array(2) {
  [0]=>
  object(MBViews\Renderer\Term)#3005 (3) {
    ["meta_box_renderer":protected]=>
    object(MBViews\Renderer\MetaBox)#2037 (0) {
    }
    ["data":protected]=>
    NULL
    ["term":"MBViews\Renderer\Term":private]=>
    object(WP_Term)#3006 (10) {
      ["term_id"]=>
      int(3)
      ["name"]=>
      string(24) "ทาวน์โฮม"
      ["slug"]=>
      string(8) "townhome"
      ["term_group"]=>
      int(0)
      ["term_taxonomy_id"]=>
      int(3)
      ["taxonomy"]=>
      string(16) "wd_portfolio_cat"
      ["description"]=>
      string(0) ""
      ["parent"]=>
      int(0)
      ["count"]=>
      int(2)
      ["filter"]=>
      string(3) "raw"
    }
  }
  [1]=>
  object(MBViews\Renderer\Term)#3007 (3) {
    ["meta_box_renderer":protected]=>
    object(MBViews\Renderer\MetaBox)#2037 (0) {
    }
    ["data":protected]=>
    NULL
    ["term":"MBViews\Renderer\Term":private]=>
    object(WP_Term)#3008 (10) {
      ["term_id"]=>
      int(4)
      ["name"]=>
      string(54) "บ้านแฝด / บ้านเดี่ยว"
      ["slug"]=>
      string(26) "single-semi-detached-house"
      ["term_group"]=>
      int(0)
      ["term_taxonomy_id"]=>
      int(4)
      ["taxonomy"]=>
      string(16) "wd_portfolio_cat"
      ["description"]=>
      string(0) ""
      ["parent"]=>
      int(0)
      ["count"]=>
      int(2)
      ["filter"]=>
      string(3) "raw"
    }
  }
}

When I run the same query with get_terms in PHP, the result is:

array(2) {
  [0]=>
  object(WP_Term)#3069 (10) {
    ["term_id"]=>
    int(3)
    ["name"]=>
    string(24) "ทาวน์โฮม"
    ["slug"]=>
    string(8) "townhome"
    ["term_group"]=>
    int(0)
    ["term_taxonomy_id"]=>
    int(3)
    ["taxonomy"]=>
    string(16) "wd_portfolio_cat"
    ["description"]=>
    string(0) ""
    ["parent"]=>
    int(0)
    ["count"]=>
    int(2)
    ["filter"]=>
    string(3) "raw"
  }
  [1]=>
  object(WP_Term)#3228 (10) {
    ["term_id"]=>
    int(4)
    ["name"]=>
    string(54) "บ้านแฝด / บ้านเดี่ยว"
    ["slug"]=>
    string(26) "single-semi-detached-house"
    ["term_group"]=>
    int(0)
    ["term_taxonomy_id"]=>
    int(4)
    ["taxonomy"]=>
    string(16) "wd_portfolio_cat"
    ["description"]=>
    string(0) ""
    ["parent"]=>
    int(0)
    ["count"]=>
    int(2)
    ["filter"]=>
    string(3) "raw"
  }
}

I’m not sure if this is a bug or something I’ve missed, but I expected both outputs to be the same because I cannot get data in protected property. Could you advise on this?

Thank You.
