JabRef version

Operating system

Details on version and operating system

Checked with the latest development build (copy version output from About dialog)

• I made a backup of my libraries before testing the latest development version.
• I have tested the latest development version and the problem persists

Steps to reproduce the behaviour

1. Search for duplicates
2. The counter makes no sense

What are those numbers supposed to mean? The left one keeps incrementing when duplicates are merged.
