Refresh Zotero and references now missing!
Zotero is somehow deleting articles from my reference list and also rearranging the order after I exit from Word or refresh, or when adding new references. I had to add some references manually - from websites, or others I had added before getting Zotero. Now they are missing from my reference list!! I try and put them back in alphabetical order as well and next thing I know, they are back in a different order (usually the ones I typed manually into word are mixed up as I assume Zotero is only putting the references it used in alphabetical order). Frustrating!!
If you really need to add uncited items to the bibliography, you can use the Add/Edit Bibliography button and add items from your library, but generally you would just insert citations into the document and they would be included in the bibliography automatically.
