Hi Emiel, does the microflow that retrieves the images also fetch 4 objects/images? Or do you only see this in your modeler? You can limit the number of colums to 1, or if its always only 1: turn it into a dataview. Otherwise, in your microflow you can check if the objects are distinct and if not, filter/edit the list before it is fed to the template grid. If your page show 4 identical images however when only 1 should be retrieved, it sounds like a bug somewhere in your app is duplicating the objects.
Hope I understood your question correctly, good luck!
