Text Formatting ⇒ reference format not follow sequence number

[yana819]

HI

I'm using overleaf and ieee trans format, unfortunately my reference number is not follow the sequence as shown in Figure below.

Here is my reference code

Code: Select all

\bibliographystyle{IEEEtran}
\bibliography{reference}

but the number is follow the sequence when I insert

Code: Select all

\newpage

, but this way cannot be used and weird if they have too much empty space.
