Endnote output is different in text than what is specified in output style


I am experiencing a problem regarding intext citation.

Many authors are cited in the text, but I want only one author and et al for following authors than the first author. I have generated a new output style and the selection is clear but I repeatedly get the same problem.

Please notice the intext citations in the picture below. It’s so random. Somewhere it is one author followed by et.al. and somewhere it is 3 authors and then et al.

I am using Zoonoses and public health output style.

Can anybody help how to troubleshoot this problem ?:womansad:
