Submissions doesn't order by finished time

My instance is on 2.9.0.beta10 (ff42bef1b6) and the wizard is 2.0.0, submissions used to listed by the time users finished all fields, but now new submissions seem randomly inserted into the existed list, and all Submitted At column shows ‘-’

Thanks for the report. Please update the Custom Wizard Plugin to 2.0.2 and this issue should be fixed.
