New citations are added with a dashed line underneath the citation ID: 37020582
I am writing a thesis using MS word on Mac 10.14.6 and on my large documents I have been working on for multiple years, citing through Zotero no longer works (Zotero has been updated to most recent software). In these large documents, if I insert a citation, it appears in a different font with a dash underline (on a new document citing works normally). On my existing documents more often than not when I attempt to cite the Zotero client pops up to the front of the screen and I cannot make the original citation even when I navigate back to MS word. Help appreciated!
A dashed underline under citations would be from "Automatically update citations" being disabled. You should be able to test that in a new document to see exactly how it works. If something Zotero-related isn't working in a specific document but it works in new documents, see Debugging Broken Documents.
