How do I remove podcasts fro iTunes when they show iCloud icon?

I added iOS 7 to iPhone 5 and latest iTunes 11.1.0.126 to laptop. I load music and podcasts onto iPod Classic 160 GB. Problem is--after this update, some of my subscribed podcast episodes are no longer on hard drive---but show in iTunes with the iCloud icon. In fact some previously listened too podcasts, since deleted are shown also with iCloud icon---which busies up my list with unwanted old podcasts. I CANNOT DELETE THEM OR MAKE THEM GO AWAY! I don't even care about getting the ones I hadn't listened to back. I just want to clean up iTunes to eliminate them from showing at all and secondarily do not want them eating up any iCloud space. Note: I am NOT enrolled in iMatch. My iCloud control panel only shows about iPhone. I have no idea how to see or access iCloud for iPod Classic and don't know how it was even established in the first place.

Help!! Bottom line: I want to delete/remove all podcasts showing iCloud icon. Even when I download them to harddrive (which is a problem as I'm on limited GB monthly use being on a satellite), I still cannot delete them.

Thank you.
