Ambiguous Author name when there is only one instance of that author

EndNote EndNote How To
1

Seems a complciated question…

  1. Using APA 7th, under Bibliography, the rule to deifferentiate ambiouous citations is to include the author name instead of initials).

  2. I got result of a citation in my word file:

Kok, P., Bains, Lauren J., van Mourik, T., Norris, D. G., & de Lange, F. P. (2016). …

And this is the corresponding Author in EndNote X9

Kok, Peter
Bains, Lauren J.
van Mourik, Tim
Norris, David G.
de Lange, Floris P.

-> Why is Bains, Lauren J. not initalized. but Norris, D. G.

3.  I suspect it is related to duplicated authors.

So I search: Search Whole Library, Any Field, Contains, ‘Bains’

Only the above record pop up.

I also does not have Trash.

  1. I checked the Term list:

There is only one Author named:

Bains, Lauren J.

no other ‘Bains’ in the record.

So why does Endnote think that I have an ambigous author that requires full name instead of initalis normally?
