Zotero Journal Abbreviations not working (File Renaming)

neilster

I recently want to try and use zotero to make it easier to rename and organise my lit database. I wanted to rename them as "First author - Year - Journal Abbreviation - Title truncate 100" i was able to get it working but zotero does not abbreviate the journal and just puts the whole journal name in there.

It puts the "Journal of Periodontology" not JOP or anything else

what is the best way to fix this?

Thanks!
