I have a main collection called "Fenster". This collection has a column "Farbe" containing multiple references to a collection called "Farbe".
By selecting an item from my main collection, the column containing multiple references doesn't display anything. Both collections - the main collection and the referenced collection - have been synchronized.
Can somebody figure out what's the problem here?
See pictures for better understanding.
Thanks and greetings,
