In Second Shootr 1.2, every module has groups, so you can organise your data better. If you have migrated data from a previous version of Second Shootr, the app doesn't know which group the data should go into, so it moves it into the Ungrouped Data folder. You can move it from there if you wish.
If you're still unsure on these steps, either ask in the forum, or create a new ticket to contact support
