I don't remember seeing this question.
You are correct that the lack of a date is the problem. That should not have happened - you can't do that if you tried! On the plus side, there is no harm except for the annoyance of seeing that Void check on the list.
Do you have an Adagio consultant? If yes, do they have Adagio GridView Read/Write? That's what is needed to fix this problem, and it is a simple fix. You will want to give them your data and have them do the repair. (Alternatively you can buy GridView Read/Write but I highly doubt it is worth it in this case).
