The custom set number of results per list doesn't apply to member lists for alliances, when you go from the alliance page. I have mine set to default at 50 results and it presents at 10. Again not a major thing, just something out of the expected.
So to better explain. I went to Rose's Alliance page and then scrolled down to the Basic information box, went to the line with the number of members, and then clicked on the list button beside 92. This gives you the 10 results. Interestingly enough, If you use the alliance buttons ( the ones above the Basic information box) to view members, it does give your default number of results. Also confirmed it's the same with all alliances, not just Rose Sorry I can't provide a screenshot, but hopefully i was detailed enough that you can understand.
