Strange behaviour inconsistency between json and binary data

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)?

Please share your workflow

## Share the output returned by the last node
<!-- If you need help with data transformations, please also share your expected output. -->

## Information on your n8n setup
- **n8n version:**
- **Database (default: SQLite):**
- **n8n EXECUTIONS_PROCESS setting (default: own, main):**
- **Running n8n via (Docker, npm, n8n cloud, desktop app):**
- **Operating system:**

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.
