Hi.,
It is a little bit hard to say without seeing your full project but my guess is that you are using the DONE button to leave the form and go back to the data viewer. When leaving the entry form and data has changed, you would be prompted to "Save record". If you say yes to that, it will save that last (3rd) record as somewhat incomplete as reflected in your data.
I apologize that I cannot be more specific but that would be my guess.
Thanks.
