Strange behaviour inconsistency between json and binary data

[Pechi77]

Describe the problem/error/question

In input side I have 9 items, after removing duplicates, I see 3 items displays fine on output JSON,
When I click output side Binary, it just shows only one File, but it should display all 3 different files.

Attaching my image and providing workflow, kindly help.

What is the error message (if any)?

The remove duplicates node only worked for me, if the binary files had different names, but normally they are named “data” only. Using Script in a Function node was my way to go and use file names to filter out the duplicates by filename only.
