Was scratching my head for quite a while. You typo'd the pubDate as "Febuary". (For some reason amethyst won't upload a screenshot)
When I can't figure out the date I use the current date instead of 12/31/1969. Which is always today (everytime I scan).
If you fix the typo and "Scan Now" from
https://ipfspodcasting.net/Feed/53/Podcasting4Value it should fix on the next scan.
