While pushing the entries into Jabref library through Websearch, the name of journal and year of publishing are going to the optional field instead of required field. Thus, the journal name and year information gets missed in references in the latex document.

Kindly guide how to add this to main field. I cant find the "customize entry type" key in "Options" tab. I am using latest version: JabRef 5.0-dev--snapshot--2019-07-29--master--f6eb5344a Windows 7 6.1 amd64.
