I'm also seeing duplicate episodes in the RSS feed and in the manage episodes listing. Episodes 1-7 are triple listed and episodes 8-20 are double listed. I was submitting my show to the Podcast source App (Libsyn) it failed because the feed did not validate. I checked the feed by checking it from the dashboard, the check feed in new window tool. And the listings are doubled and tripled. I copy and pasted the feed into W3C feed validator and it does not validate. I have made no changes other than uploading my next episode. I use the blubrry player code that I paste into my Squarespace web page. I do not host media on Squarespace, it's on blubrry. I have no idea what happened. I would like this problem fixed so I can continue to submit my show onto other listings. The duplicates also show up in the blubrry directory. I do not know what do try.
