Hello,
I am trying to create a gallery in which I can search and select from the list, I have seen some video how to do this but I have a problem in one point. when I make the drop down menu and link it, each entry in the list appears multiple times instead of once as it should. As you can see below instead of the "LG" entry showing once and when I select it to show all the entries with "LG" it shows the word "LG" several times in the dropdown. The same happens with all entries.

I created the gallery from a sharepoint list. The sharepoint is from an imported excel.
