Thanks Leanne for the reply.
I use Vancouver style (plain font selected in endnote). In the bibliography, Times New Roman, font 12 is used. I did not have this problem before but this time it seems to have problem after 99. I tried every setting as you suggested and yet 100 onwards look differently with 99 and below. It seems there is a different type of ‘tab’ symbol between these 2 sections, but it is the same endnote library, same reference type, same document, same computer.
I did try to change to different output style yet same thing. My setting for the hanging indent is same as yours, 1.27mm.
