Contextual menu in the editor panel

At one point I was able to use contextual menus ( right-clicking on a two-button mouse or ctrl-clicking) in the editor panel. There were some useful options like changing the title case, etc. However, I lost this ability at some point. Contextual menus still work in the main window and the preview window. Any way to fix this or any way to access those options otherwise? I’m using version 5.7.60000 of JabRef with MacOS10.15.7, but the same issue was present in v. 5.6. Thank you!


this might have probably something to do with your macOS version, I am on BigSur with a MacBook and all looks fine to me:
