Errors when editing ls token using entity administration and history

Perhaps this is an unusual use case, but trying to edit pre-existing tokens that had worked (somewhat) in the previous version, after clicking edit, I get:

Warning: date_timezone_set() expects parameter 1 to be DateTime, boolean given in format_date() (line 2062 of /srv/bindings/8dbba19192124a1c8ddcdfff90761e4b/code/includes/common.inc).

After adding the user to the token and clicking update, the date-timezone errors go away, but I still see the array_flip errors.

Thanks.
