Double custom fields

[marvays]

Hi.
I have problem in product detail page. All custom field are double. Where is the problem?
I am using Materialmart template from flexiblewedesign. Latest joomla and VM.

Code in template abou custom field is:

<div class="ThinBorder my-4"></div>
      <?php echo shopFunctionsF::renderVmSubLayout('addtocart',array('product'=>$this->product, 'params'=>$params, 'layout'=>'productdetails'));?> </div>
  </div>

First try with a standard template

The standard template Vm is fine. I tried that first.

For 3 years I've been using CleanMart without any major problems. I have now bought MaterialMart from the same company and I have almost 10 serious problems on one site

Then they must fix them...  they are commercial templates
