You already have those from the node feeding into List.CountOccurances don’t you?

Maybe you should try List.Sort instead?

That’s a bit weird. Then u can try to set lacing to shortest. Or also you may chop unique elements list by using List.Chop before connecting to OfrepeatedItem node

This is a more appropriate solution. It seems you already have everything, you just need to sort it. Right now, you’re removing data only to add it back.
