Q: One of my podcast episodes won't show up on itunes!

Tumblr feeds are not 2.0 compliant and google drive is not appropriate for hosting podcasts.

You should look at a true podcast host for your show.

You appear to have hit the same glitch in the Store that others have reported. The feed is OK, and there isn't anything different about episode 6, which does appear when subscribing. You're using Google Feedproxy, redirecting to a Google Drive URL and this is working in the itunes application but evidently you've not checked playing in the Store itself, because your episodes don't play there. This is probably the Google Drive problem - it's not a reliable place to host your media files.

As to the Store problem, there's nothing you can do yourself. You can report it to Support (though they probably know all about it by now). Go to https://itunespartner.apple.com/en/podcasts/overview and click the 'Contact Us' link at the bottom of the page.

As long as you don't change the 'guid' tags there are no problematic implications. People who have already downloaded episodes in iTunes will retain them and won't download them again. I'm assuming that you aren't proposing to change either the Feedburner feed or the original Tumblr feed.

Within your 'enclosure' tags the 'length' attribute is "-1". It should be the file size in bytes: obviously no file size can be a negative number!.

Your 'itune:subtitle' and 'itunes:summary' tags have HTML, such as

We’ll help you figure out

This is incorrect anyway as the opening '&' of a code sequence has been converted to the code for an ampersand. It's not a fatal error, but iTunes will probably display the code. You should replace it with a simple singe quote from your keyboard. These tags should contain plain text only.

You can ignore the 'misplace item' - this is simply a layout issue because the 'item' tags don't start a new line. This doesn't affect how the feed actually works. (The feed is mostly all on one line, which makes it very difficult to read.)

The text I quoted is in the 'description' tag in the original feed, so perhaps the Feedburner feed has populated from that. The problem is probably that the text has been submitted with the html code in place - ’ - and Tumblr has treated the code as if it was text and entered the code for the ampersand (which is necessary because you can't have an ampersand by itself as it wrecks the feed). A common mistake is to write the text in a word processor and then paste it into the method for constructing the feed, whereupon formatting codes and things like curly quotes make problems.

You must have written that text into Tumblr somehow in the first place, so you need to replace it with plain text. Either that or write the text you want into the Feedburner tags in the place FB provides for doing that.

What about that enclosure size error? How can I edit that?

You would have to tell Feedburner that - you've submitted the media file URLs to it and it's then routed the requests through Feedproxy. I would have thought here should be a place where you can enter the file size. (If you're using a Mac you can get that using Get Info (command-i).

The Tumblr feed doesn't have any 'enclosure' tags, that's been done in Feedburner, either drawn from references in the Tumblr feed or because you entered the media file data in Feedburner. So any amendments to that need to be done in Feedburner.
