RSS Feed not Sorting properly

I have this RSS feed that working fine on a Block,  but it is not publishing the latest/top feed first.

This is could be a simple process where the query needs to be modified to retrieve the feed in ascending order by the date, but I am not too familiar with Dolphin source code and where to find things..

Please let me know if you have expertise with RSS/XML programming & wish to assist..

Thank you.
