Sometimes this is due to the fact that the underlying font defined in the document template is different and text has been selected and had a different font assigned to it manually. then endnote inserted refs may be picking up the underlying font rather than the “text assigned” font.
I just created a new document with no formatting changes, and added two different citations. The one that is often wrong in other documents remains ill formatted, whereas others are displayed as they should.
Okay. I think it is then likely that you have somehow gotten font specified in the record itself, which can happen in some versions of endnote, if you copy and paste from somewhere else? It should be “plain” font in endnote. You can look for some suggestions and details in this thread.
I don’t think it happens anymore, I think it was a “feature” that crept into one of the earlier versions of endnote… - Once Identified, they fixed it pretty quickly.
