Problème avec yj_vm_latest

Hello,
I have a problem with the module on the site yj_vm_latest youmania with the ProduJardintemplate that I bought there is more than a year. So I have more support subscription.
I just discovered the following problem:
When I want to display a product that has different prices depending on quantities, if I chose to display 3 products, the module can display 3 times the same product with different prices, I choose the category ID or product ID, the problem is identical.
Have you a solution for the module displays only 1 time each product and with the smallest price in case the products have different prices depending on quantities.
Thank you for your help
Christian
