Unabbreviation doesn't work

Hello, JabRef users and developers!)

I with a problem: after applying the abbreviations for journal titles in the application, I cannot execute unnabbreviation procedure:

  1. click 1 time on toggle button - get abrriviation
  2. click 2 times on toggle button - get more abrriviation
  3. click ‘Unabbreviate Journals names’ tab - get this message :1

Hi, could you give an example of a journal that can be abbreviated twice?

(if I understand you correctly, the issue seem to come from a journal being abbreviated two times)
