I did some research on my own and it seems to be an iTunes issue and nothing with the podcast or the upload. Weirdly some itunes accounts just can't download an episode and there is no exact reason why.
If you are still having issues unsubscribe delete 18 if it is showing in your feed and then resubscribe and try again. I did that and suddenly it worked!
