[EndNote X9] Electronic publications and wrong pages numbers in bibliography

Dear EndNote Community

Firstly, sorry if my message appears twice, I was sure I posted it but it seems to have disappeared.

I am a recent user of EndNote (but an old user of Reference Manager 12) and I am struggling with an issue in my customized output bibliography style.

For some papers I have pages numbers shown as ‘e00209-18’. However, in my Word document, they appear as ‘e00209-00218’ in my bibliography. I don’t understand why it changes itself on its own, has this happened to anybody before? How did you address the issue?

Thanks for your help!
