ODK COLLECT form validation

Hi,
When I am using ODK Collect app for data collection. I have an issue. I have a subtype(EVENT_GROUP) in my xml form, the values of which are present in a CSV file. when I open the file in my android app, the subtype (with the options) is not visible though I have selected some option from the main group. It becomes visible only when I click some other button(say button for getting geographic coordinates(START GEOPOINT) or image capture button(TAKE PICTURE)) in my form. Can anyone tell me how to make the group(subtype) visible always?

You either have bad logic in your form or are grouping multiple dependent widgets on a screen. Without your attached XLSForm, it's hard to help.
