Changing playing Order in Overcast Podcast player

I am using the latest version of Overcast on an iPhone 6S with the latest update of iOS 9. I use Overcast listening to podcasts individually rather than using the playlist mode. All of my podcasts used to list episodes from oldest to newest, which is what I prefer. But recently, the order has been reversed playing newest to oldest. Is there a way to reverse the playing order again? I can't find anything in either the individual or general podcast settings to change this. Thanks for any help.
