APA 6 or more authors, et al question

Thanks for your reply – yes, I just checked the Biblio section too, and
all three are unchecked.

I did try just editing in the text, as suggested in another post somewhere
on this forum, and that seems to have worked, even upon save-close-
reopen. That seems like the “bigger hammer” approach to me, though.

Any other suggestions are most welcome!
Thanks,
anne
