1-8 instead of 1,2,3,4,5,6,7,8

I’m having difficulty getting the consecutive citations function to work when working my manuscript in MS-Word . I have the option “Use number ranges for consecutive citations” checked, but the citations are still listing every citation (i.e., 12-13-14-15-16) rather than giving me a range (i.e., 12-16).

Can anyone help?


please zip your output style and attach so I can have a look at it?
