Generated Key contains 'null' when (corporate) author contains several special words after curly braces

JabRef version JabRef 5.0--2020-03-06--2e6f433 on Ubuntu 19.10

• [x] I have tested the latest development version from http://builds.jabref.org/master/ and the problem persists (JabRef 5.1--2020-05-08--40f908f on Ubuntu 19.10).

Steps to reproduce the behavior:

1. Add the attached reference to a database
2. Check database integrity
3. Get notified of difference ("BibTex key deviates from generated key")
4. Go to mentioned key, click "generate key"
5. The key will now be "nullL2019".

Sample Bibliography

  url       = {https://youtu.be/sBSwJ6HOBG4},

Log File

No events were generated in the event log, even though I followed procedure according to [the docs](https://docs.jabref.org/general/commandline), and I ran both the `.deb` and Portable versions (the latter I ran with the following options: `./JabRef --console --debug`). This was the output on the terminal: ``` ERROR StatusLogger Unrecognized format specifier [d] ERROR StatusLogger Unrecognized conversion specifier [d] starting at position 16 in conversion pattern.

Thanks for your report. It would be helpful if you could tell us which key pattern you have defined for the entry type or if you are using the default pattern

[rolandog]

Hi @Siedlerchr ! Thanks for your reply!

I don't think I have modified the defaults;

If I click on the 'reset' button on the entry, a value of [auth][year] appears, instead of a blank value... but the behaviour is the same: the entry's generated key still contains null.

This may or may not be helpful, but I noticed that most of the "corporate" authors are not displayed properly; here's a screenshot on how the column is displayed for the author {Commission on Isotopic Abundances and Atomic Weights}:

I don't think I have any odd settings on the 'Entry Table' settings:

Just to be on the safe side, I reset all my preferences, restarted JabRef, modified the entry's key, re-generated it and got the same results; also the same problem was present with the format of the corporate author's name in the author's column.

Tomorrow morning I'll try uninstalling, removing configuration files, and see if there are any different results.

[Siedlerchr]

Thanks for your feedback! Resetting preferences was enough as clarification. Looks really like a bug,

I can take a look at this?

[Siedlerchr]

@k3KAW8Pnf7mkmdSMPHz27 Sure go ahead

Thanks to @k3KAW8Pnf7mkmdSMPHz27 this should be fixed in the latest development version. Could you please check the build from http://builds.jabref.org/master/. Thanks! Please remember to make a backup of your library before trying-out this version.
