Wrong URL for itunes image

[Sensei Geek]

My original feed is: https://www.sensei-and-the-geek.com/podcasts-itunes.xml

My FeedBurner feed is: http://feeds.feedburner.com/SenseiAndTheGeek

In the original field I have the following tag:

<itunes:image href="https://www.sensei-and-the-geek.com/sites/default/files/sensei-and-the-geek-square.png"/>

However, my Feedburner feed showing is:

<itunes:image href="http://www.sensei-and-the-geek.com/sites/default/files/japan-flag-square.jpg" />

This href is old.

I've tried pinging my server, and I also clicked the re-sync link on the Feedburner site, but it still shows the wrong image.

How can I get it to properly update the image URL?

I've read a bunch about Feed burner, and it sounds like it's pretty much on the verge of death, so I've decided to stop using it.

Problem solved.
