Are you syncing, or is the iPad your only client? Can you show us the dates tab for the recurring action(s)? I'm not quite sure I understand the first part of your report.

The second part makes sense, however. Repeating tasks have the next task created when you mark the current one complete. If you subsequently go back and unmark the current one complete, it will not destroy the one you've made, so you will end up with a duplicate, unless you unmarked it with the Undo function. Just tapping the checkbox again will not do what you want.

You can simply delete the unwanted duplicates.
