Vancouver style

Feb 3 at 7:15 PM
(word 2016 macOS) I don´t know if I'm the only one with this error but... When using Vancouver style is the reference number in the text is supposed to be in "super index" format and without parenthesis. But it isn't like that, it appears normal and with parenthesis, there is any way to solve this? Am I doing something wrong??
Thank you for you help. And for all your work!
