My Feedburner Podcast Feed is a Total Mess -- Please help!

[JH]

Hello,

My podcast RSS feed is missing all sorts of information that's preventing it from uploading properly. Most notably, it's missing a valid valid <enclosure> tag, along with several other items. I did nothing to cause this--they just stopped uploading one day. How can I ensure my feed has EVERYTHING that is needed to upload to Apple & Spotify? Do I have to do this manually or is there a process or service that will do this for me? Please see the attached screenshot for all that is missing (see red X's). 

Thank you so much!!
