Creating automatic sequential lists in Pages for iOS

Maybe I'm crazy, but I am having difficulties with creating lists that work in Pages for iOS.

I am a teacher, and I have been trying to use my iPad in the classroom more. I have been trying to make simple multiple-choice review quizzes using Pages.

It seems that when I create a new list, the numbering works fine. 1, 2, 3,... No problems. When I try to add an indent with A, B, C,...etc., the number I had completely reverts to the 1. It doesn't continue to keep the sequence. And I have no control over what number comes next like on the desktop version. Am I doing something wrong, or is this a bug?

Thanks.
