I have the impression Zotero does not recognise its previous references. It only recognises the latest 3 references I added and only adds those to the bibliography. The previous references are still in the document though. When I change the citation style it only updates those last 3 references. I have no idea how this could have happened. Working on a Mac in Words, using Zotero 5.0.89-beta. The plug in buttons also don't work properly and I sometimes have to double click them before they do something, sometimes they don't do anything at all. Thanks for your help..
