How to remove duplicate products in Virtuemart 2 category (pagination)?

Question

Joomla

Maybe someone faced such a problem. There is a custom category in VM 2, on the page with this category, an additional CherryPicker module is displayed.
So, at the initial loading of the category, there are duplicates on the pages, if you set a lot of goods (more than there are) in the pagination settings, then the goods are displayed without duplicates, i.e. if pagination breaks a product into pages, then duplicates appear, if it doesn't, then there are no duplicates.
Joomla cache is disabled, I did not find a way to further disable the cache of Virtumart (is there a way?).
VM Version 2,6,6 + Joomla 2.5

Answer 1

I answer myself. There are many posts on the Internet with such a question and without an answer. The case is not isolated. In fact, there are jambs with pagination and cache in Virtumart, but this is what became my solution. The CSVI component for importing products and categories was installed on the site. Through it, I imported parent and child products. This was the rub. Import did not go perfectly, although external signs were almost invisible. After observing the process, I concluded that often the articles were mixed or not prescribed, as a result, there were goods (parents and children) not related to each other. In my case, the separation of imports helped me - first the parent products, then the child products. A separate image file for the goods. Only in this way the import was correct and duplicates stopped appearing.
