Key field entries missing in table

I’m running JabRef 3.8.2 on a Retina MacBookPro, 15", Late 2013, 2 GHz Intel Core i7, 16GB RAM, OS X 10.14.1. All the key fields in my table are empty, even though all my entries, save a few, do have [author][year] keys. I’ve searched my preferences for some way to make them appear, but I am not able to do so. I’ve attached a screenshot showing the problem.



Whoops. Here’s the graphic.


You need to generate these keys by selecting the entry(ies) and pressing the key symbol in the toolbar.

Hi Tobias. Thanks for the suggestion, but it does nothing. When I have an entry selected and I hit the key symbol, the program seems to take a second or so to do something and then nothing changes. See screenshot, which shows an entry with a pre-existing key after I had hit the key symbol. The key does not appear.

Ok, gauging from your screenshots, the entries actually have keys but they are not shown. I guess the problem is that the column reads key but it should be bibtexkey. You can change this under Preferences > Entry Table Columns.

I knew it had to be something simple, but indeterminable by an old professor like me!

Thanks Tobias!
