Products shown twice

-- url of the page with the problem -- : www.oldehoofsterkaasboerderij.nl/index.php/bestelformulier
-- HikaShop version -- : 2.4.0
-- Joomla version -- : 3.4.1
-- PHP version -- : 5.3.10
-- Browser(s) name and version -- : Chrome

On this page, all mij products are shown twice: www.oldehoofsterkaasboerderij.nl/index.php/bestelformulier
From top to bottom, the page contains:
1. a description of the category
2. social plugins
3. products in table-layout (configured via menu-manager --> details)
4. products in table-layout configured via Hikashop --> system --> show --> Modules hoofd standaard opties)
Where do I switch off the last view??

Thanks!

Update! I already figured it out: the last view disappeares when choosing 'brand' in stead of 'product' in the Associated products listing-options
