Date Error When Adding New User

Overview: Added a new user and assigned some dates (date enrolled and date expired) using date picker which showed mm/dd/yyyy as the format. Saved the new user and got an error seemingly related to date format.

Steps:

1. Log into folio-testing
2. Create a new user and populate date enrolled and date expired by picking dates using the date picker (which should display mm/dd/yyyy as the format)
3. Save the new user

Expected: Saves without error

Actual: Saves but attached error displays

Additional Info: I checked Settings > Org >Language and localization to see which locale was selected and nothing was selected.
