Virtuemart custom field changes all products

Hello again

I have Joomla 3.7.0 with virtuemart 3.2.1. And I have problem with the custom field cart variant. When I am at Best Sellers module and change from dropbox the size in ml, the price changes in all products. And whatever I choose it changes all the prices again. Also when I am at the category page of products the price doesn't change when I choose from dropbox.

I still can't fix this. Any solution?

Could you please send infor access to email contact@omegatheme.com
I'll check the issue.

Regards,
Kien
