Ok, I am totally new to Jabref but I am not new to programming etc. That said, I am trying to create a export filter to format some a .bib into a .csv. I went to the jabref help and to [https://cynthiadangelo.com/2012/10/22/exporting-mendeley-tags/](https://cynthiadangelo.com/2012/10/22/exporting-mendeley-tags/) in order to figure it out. I created a new .layout etc and Menu Options – Manage custom exports – Add new But everytime I export I get exactly the same output I do see in the drop down menu for export there are two .csv outputs listed but neither have the name I gave it when I “Add new” I have tried all kinds of things, now I am beating my head against the wall. I am missing something simple?

Hi,

you did all right 😉 In the current 4.2 there’s a bug with the selection of the custom export filter.  
The good news, there’s already a fixed version.  
You need this special development version.  
[https://builds.jabref.org/fixCustomExportFileType/](https://builds.jabref.org/fixCustomExportFileType/)

For reference: [https://github.com/JabRef/jabref/pull/4015](https://github.com/JabRef/jabref/pull/4015)  
The fix is not yet merged into master, but we are working on it.

Regards  
Christoph
