The table lists all of the tasks available for you at the moment and those you already have completed. You can apply filters above the table to leave only tasks you are interested in at the moment.
There are 5 statuses tasks may have:
New — tasks waiting to be completed by you
Pending — tasks you’ve already opened that haven’t been checked for completion yet
Completed — tasks you’ve successfully completed waiting to be paid for
Paid — successfully completed task, you’ve already been rewarded for
Check failed — tasks you’ve opened, but haven’t completed. You can open them again to complete
