Option to deploy to android app not active

i did upload my XLSForm successfully and even deployed it. However when log into my account, then go FORM—>Collect data, to the drop down to select Android Application does not change from the default “online-Offline (multiple submission”. Whatever you select, it doesn’t change. may i know why and how i can get around this?
Thank you
