We were able to identify that this issue is only affecting our UI and it's related to a third-party library. We have decided to push-back this update. No leads are lost and the correct dates will be updated on the new year.
We are sorry for any inconvenience this may have caused. If you have any questions, don't hesitate to reach out to us (firstname.lastname@example.org
UPDATE: The issue has been fixed and all the dates should be showing correctly in the app at this point.
