[solved] How to customize entry types permanently?

used to use JabRef a lot in my studies around 15 years ago, I returned recently to my old database. Now I use JabRef version 2.10b2 on Kubuntu 14.04 LTS. Every time I start JabRef regardless with my old database or with a new one, I have to customize the entry types to my preferred order. If I confirm with “OK” or “Apply” the order is valid for the actual session. After restarting JabRef the order is again alphabetically. How can I fix my preferred order permanently?
I discovered that my self-defined entry types are placed at the end of the bib-file. Here is tried to set my own order for my entry types as well I add the order for the predefined entry types. JabRef uses the entry types, but not the order.
How to customize entry types permanently? Thank you for your assistance.
Best regards,

Hello Bernhard,

welcome to the forum.
You are using a very outdated JabRef Version which is no longer supported.
Please try again using the newest version 3.5. You can get it here: https://www.fosshub.com/JabRef.html
Just a notice, it requires, Java 8 to work,


Hello Christoph,
thank you for your welcome.
I replaced the JabRef Version in the Ubuntu Repositories by the new one. With Java 8 JabRef works quite well. Thank you for the solution.
Best regards,
