problem with related products

-- HikaShop version -- : 2.6.3 essential
-- Joomla version -- : 3.6.2
-- PHP version -- : 5.55

Hi guys,
i have some troubles configuring related products. I used the following documentation:

Related products : Select one or several products related to that product.

These products will then be displayed as a products listing at the bottom of the product page thanks to the "Related products" module that is pre created by HikaShop and enabled in the "Modules under the product page" setting of the HikaShop configuration. You can edit that module via the menu Display>Content modules if you want to change the display of the related products.

Also, if you activate the "Make product association in both ways" setting of the HikaShop configuration, when you add related products to a product, that product will be added in the related products setting of these products.

Here is an example of the result on the product page:

Hi Nicolas,
here are the settings of the module

Hi Nocolas,
and here the Module settings under the productpage

And the productpage

IT WORKS.

The setting in the productpage was not saved properly
