@Banackock after reviewing the logs, I've discovered the reason you got this error is that while you had all of your items in to claim, but you also had an extra 'form' where you only entered the 'Week Ending' and nothing else. The system will ignore any extra empty forms, but because you selected a date, it saw the form as non-empty and therefore gave you an error because the rest of the fields were blank.
Now it should have given you a more friendly error message so I'll work on that, but in the meantime, just make sure you don't try to submit any partially-filled items and you should be good. I will also need to add a button to clear the date-fields on Bulk Claim since currently there is no way to remove a date once you select it without refreshing.
