Hi, once my article was almost complete I changed the output style of Vancouver to [square brackets], as this was the requirement of the journal. This worked except that it also added squares within the brackets that I needed to manually delete (not ideal but manageable). Now if I want to add a new reference, it sets all the previous ones to [1] registering it as an invalid citation, and marks the new Ref. as [2]. I’ve tried setting it back to the regular Vancouver, but then it also changes all Ref. to (1). Any ideas what the issue/solution could be? I really want to avoid needing to manually insert these or leaving them out all together…
