Previous & Next buttons not inline with listed products

Hello … First of all, great plugin, thank you very much. Wonder how it may change a little bit.
Let’s say you have a product page, with products A, B, C, D, E … click on a quick view of product C. While in quick view, click on the next button, the next product would not be D, or click the previous button, and the previous product would not be B. Where in the code may I change so it is in line with the products?
I thank you very much for your time.
