iTunes is not showing my enhanced podcasts url links

Hi Guys,

I have searched this forum a lot, but cannot find my answer.

I'm using Garageband 5.1.

I've created my enchaned podcast in Garageband and everything is working fine in the preview. Once I export the cast to iTunes the links are no longer visable over the artwork.

I've tried shortening them using bitly and updating them in garage band but nothing seems to work. Not sure what else to try,

Can anyone help?

Thanks in advance.
