The separate songs in two page mode feature is the only thing that should impact what you are describing. If you have the page turn mode set to turn one page at a time, and separate songs in two page mode is disabled, then it should go [A1][A2] -> [A2][A3] -> [A3][B1]. I just tested this with one of my setlists on my Android device, and it operates in exactly that fashion. If you are saying the app is behaving differently for you, then I will need to see a short video demonstrating the issue, as I'm not sure what is different about your setup.
