Small warnings on Domain Mapping

Using more than one IP in the "Server IP Address" field, generates two warnings on the " DNS Configuration" from the "Mapped Domains" tab:
Warning: preg_split(): No ending delimiter ',' found in /public_html/wp-content/plugins/domain-mapping/classes/class.domainmap.php on line 322

Warning: Invalid argument supplied for foreach() in /public_html/wp-content/plugins/domain-mapping/classes/class.domainmap.php on line 323
