No page numbers shown after Ibid in OSCOLA format


I would like to ask a question about the page number issue in OSCOLA format:

According to OSCOLA, “Ibid” is used to refer to the exact same reference, while “Ibid 345” is used to refer to the same reference, but on a different page (i.e. page 345). However, when I use the OSCOLA format in Endnote to cite the same reference, no page number can be shown after “Ibid”, even though I have edited the page number with “Edit & Manage Citation(s)” function. (PS: I also tried to fill the info at “suffix” instead of “pages”, but there is still nothing shown after “Ibid”.)

Could anyone be so kind to let me know how to solve the problem?

Many thanks!
