Problem with Citations Numbering

Hi guys! I recently changed from X2 to X4. I am using the Journal of Power Sources output style.

With the X2 everything was fine but now with X4 I have some problems.

When I cite two or more references they appear together, designated by letters [1] a…, b… and I want them to appear as separate references [1,2]. The box “Use ranges for consecutive citations” is checked but I couldn’t find a way to change from letters to numbers.

One more thing: with the X2 it was fine again, now with the same output style and X4 the citations in the text are in superscript. How can I change between normal and superscript.

Thanks in advance

OK. It seems that the program is not working properly. Whatever style I choose I get the same output. I checked with some annotated style as well. I tried to make a new library in case the old version had conflict with the new version and I imported the references again but it still stays the same. I will talk to our IT department but if you have some suggestions, please help.

Thank you very much! I didn’t know that.
