title: Product is listed on database is not listed in Admin > Products List
body: <p>As an Opencart newbie, I'm adding the product with a static array just for testing the addProduct function but I could not get it to work.</p>
  
  <p>Static array:</p>
  
  <pre><code>    $data['pid'] = $this-&gt;model_catalog_product-&gt;addProduct([
          'product_description' =&gt; [['name' =&gt; 'bakbuişte', 'description' =&gt; '', 'meta_title' =&gt; 'metaraba', 'meta_description' =&gt; '', 'meta_keyword' =&gt; '', 'tag' =&gt; '']],
          'model' =&gt; 'amabigun',
          'sku' =&gt; '',
          'upc' =&gt; '',
          'ean' =&gt; '',
          'jan' =&gt; '',
          'isbn' =&gt; '',
          'mpn' =&gt; '',
          'location' =&gt; '',
          'price' =&gt; '',
          'tax_class_id' =&gt; '0',
          'quantity' =&gt; '1',
          'minimum' =&gt; '1',
          'subtract' =&gt; '1',
          'stock_status_id' =&gt; '6',
          'shipping' =&gt; '1',
          'date_available' =&gt; '2019-12-31',
          'length' =&gt; '',
          'width' =&gt; '',
          'height' =&gt; '',
          'length_class_id' =&gt; '1',
          'weight' =&gt; '',
          'weight_class_id' =&gt; '1',
          'status' =&gt; '1',
          'sort_order' =&gt; '1',
          'manufacturer' =&gt; '',
          'manufacturer_id' =&gt; '',
          'category' =&gt; '',
          'filter' =&gt; '',
          'product_store' =&gt; array(0 =&gt; '0',),
          'download' =&gt; '',
          'related' =&gt; '',
          'option' =&gt; '',
          'image' =&gt; '',
          'points' =&gt; '',
          'product_reward' =&gt; array(1 =&gt; array('points' =&gt; '',),),
          'product_seo_url' =&gt; array(0 =&gt; array(1 =&gt; '',),),
          'product_layout' =&gt; array(0 =&gt; '',)
      ]);
  </code></pre>
  
  <p>After this block, I see the entry in <code>oc_product</code> table just like others but not in Admin > Catalog > Products list. Is there another little stuff that I should prepare?</p>
