Ajax one page loading of products

[Servelatin]

Hello.
Joomla! 2.5.17
VM 2.0.26
------------------
I set one page loading of products in categories. All works fine, but then I discovered that some loaded products are duplicated with those that appear when you open a category in the beginning. Doubles gets bigger if you turn XMAP. But without him duplicate items is not lost. Error lies somewhere in AJAX handler, i think. In the database there are no repetitions, all items are unique. If you open both twins in the browser, it opens one and the same product at the same links.
Has anyone encountered this problem?
