New Post: Underline on citation

I try to create my own style based on others style to better suit the journal I publish with. However, the citation in the text always comes with a underline on the reference order. I attached the code here but I didnt recognize anything that indicate under line

e.g. [1], "1" always have a underline

thanks in advance
