Feedburner won't update

[alorentz]

I've tried all the troublehshooting steps, resynced, delete feed etc.  The feedburner feed won't update.

Feedburner:

http://feeds.feedburner.com/marketingsmarts

This is the source:

https://www.marketingprofs.com/feeds/rss/podcasts/all.xml

If you look at feedburner source, there is still a reference to 

<itunes:image href="http://i.marketingprofs.com/assets/images/logos/podcasts/marketing_smarts_1200x1200.jpg" />

However, this doesn't exist in the source feed, and is causing it to be invalid for iTunes podcast feed, since all images must be 1400+. It should be :

<itunes:image href="https://i.marketingprofs.com/assets/images/logos/podcasts/marketing_smarts_1400x1400.jpg" />

As shown in the .xml source file

Any idea why the Feedburner feed won't update, or continues to reference the 1200 px image?
