This may be a glitch in the JabRef 5.x snapshots. I don't recall which of the 28597 entries in the bibliographic database I've entered most recently, but they might also be lacking the year field. I'll ask on the JabRef dev mail list if this could be tested as I have no un-entered references now.
To follow up with the found reason: This one technical report's entry in JabRef 5.1 has an 'optional fields' tab while other technical reports have both that field and an 'other fields' tab. The Year is in the other fields tab and not available to that one document. Strange. Mentioned on the JabRef developer's list on github.
