Hi, I am inserting consecutive citations, according to the citation style (IEEE), there should be a hyphen between the consecutive citations e.g., [1]-[3]. If I insert more than two citations it works fine but when i insert two consecutive citations there is no hyphen but just a comma between them i.e., I am getting this [1],[2] but it should be like this [1]-[2].

I will really appreciate your help. Thanks
