JabRef version

5.9 (latest release)

Operating system

Windows

Details on version and operating system

Windows 10 22H2

Checked with the latest development build

• 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. Go to preferences
2. Go to external file types
3. I'm using Dutch translation and when using that translation there are duplicate file types (one written in English, one in Dutch). When the language of jabref is set to English, the same duplicate files types (in Dutch even while English is selected!) stay in the list
