e.g. in the sample data-set, "Altenwerth, Meagan" has the email address "ted@strosin-inc.cc", but if you enter "ted" in the search box the record is omitted.
I added a new user, used the date picker, for date of birth, date enrolled and Expiration date. Saved the new user, without any error messages.
When checking Settings > Organization > Language and localization - nothing is selected - the date format in the New user form was MM/DD/YYYY. See uploaded screen dump.
