List Field Bug in User Registration Update

When using the list field on a User Registration Update form -- with existing data -- the add-on fails with the following:

"array_values() expects parameter 1 to be array, string given..."

I was able to address the error by editing the following in userregistration.php (~ line 6817).

Hopefully a fix like this can be worked into an upcoming update?

foreach($value as $vals) {
						if(!is_array($vals)){
							$vals = array($vals);
						}
                        $list_values = array_merge($list_values, array_values($vals));

                    }
