Disability to add related articles

[Harryb]

I use Joomla 3.6.0 with VirtueMart 3.0.17.4

I would like to offer related articles in the webshop, but it doesn't work.

When I search for a related article in the list, there is only a list, no pictures. (I mention this because I do get to see these pictures in another webshop I use.) When I select one of the related articles and save it, it isn't saved and there is also nothing to see in the webshop.

Can you give me some advice?  Can you tell what goes wrong?

I cannot reproduce the problem.
