Ok, I did not realize that in your field so many journals use full journal names. I’ve worked in a relatively closely related field of Genomics and never encountered a single journal that printed full journal names.
Bulk editing is definitely on our radar: Bulk Editing of Papers and something we want to add eventually.
However, I don’t have a workaround at the moment other than to manually edit the titles. The quickest way would be to click on ‘Folia Primatologica’ somewhere in the list to filter for this journal and then start editing the first and click ‘Save and next’ in the edit dialog to go through the list.
