Empty option is appearing because angular doesn't recognize the select's
ng-model in options list. Since 'e' is removed from options, angular
creates a dummy item in options list. This can be verified by inspecting
the select menu in developer tools. You will observe '?' in the empty
option's value. You will have to update the ng-model of select to a value
that exists in the options. For eg:
if (csep_string.indexOf($scope.sel_val) === -1) {
$scope.sel_val = csep_string[0];
}
Please refer to the following code in plnkr:

However, your code might not be a production grade code as on each digest
cycle, "csep_to_list" function will be called. You might want to change the
itemList on input's update.
