I see a new APA style for downloading (1-03-2019) and the journal and vol are italicized in it, so I would try that (mine was okay, so not sure why yours wouldn’t be). Make sure your word document (and not the Endnote program) is set to use the new version. Make sure you name that new version something different when you save it, than the version you have now, or endnote will keep using the original. (I named mine “APA 6th (1-2019)”.
The underlying default font comes from your Word document. Endnote doesn’t specify a font. Out of the box, it seems Word using Calabri rather than New Times Roman as the “normal” character style.
