EndNote X8 no footnotes show in footnote styles

Running X8.0.0.12000 on Sierra 10.12.6 with Word Mac 2011 …

When I use a footnote style the reference appears in the bibligraphy but there is no footnote number in the text, and there is no footnote at all …

If I show field codes, then in one case the document body where the footnote number should appear I see only {ADDIN ENCITE{ADDIN EN.CITE.DATA}}

That is, there is a field containing no data.

However, after a re-install of X8 the XML data was correctly shown in the field BUT no footnote number or footnote reference is created, only the Bibliography is created.

What am I doing wrong here?

Same styles work perfectly on my Windows PC.
