Every time I insert in-text citation, it start the list over with "1". So for one sentence, I use references [1-3] and the next, I'd like to use references which should be tagged as [4-6] because they are different, but it assigns this second group of references as [1-3] as well.

Also, how do you make a change to an in-text citation list? For example, if I insert 3 references, it correctly shows up as [1-3] but when i'd like to add an additional reference in that group, it inserts it as follows [1-[1]3]. Do I have to go back and reselect all the references together?
