Hi,
Are you working on a live server? Can you please provide your website and let me check?
By the way, are you talking about the "VM - Products" module, or you are talking about the "latest products" tab that appear on the VM Front-page?
Actually If you provide me a URL where this problem occurs on your website; i would better understand what you meant. Also, since the prices are displayed correctly on our Live Demo, this problem must be specific to your website; thus i have to see things in action on your website.
Regards.
