In my Itunes I've subscribed to a bunch of podcasts, and in a few of them I have two Icons for the same podcasts, both with different podcasts. When I click on the icons neither one has the podcasts available to download from the other icon. Is there a way to combine them? Also, is there a way to get a podcast to show all available podcasts? when I click on the triangle next to the name no new shows pop up. Any help is appreciated. Thanks Jim

I have the same issue with podcasts- I have several that show up twice. I don't know if some are podcasts I downloaded from the computer, some the phone.. For seeing all of the podcasts, there should be a "subscribe" button, or a "get all" and "refresh" button
If you are subscribed, try unsubscribing, then resubscribing..: it has worked for me in the past

For podcasts to be grouped together, they need to have certain parts of their metadata be identical. To examine or edit the metadata, highlight a podcast, and then select File > Get Info.

If you look at both files, check to see that the artist and album are identical (and that they're both identified as podcasts). This is what iTunes looks at to determine whether podcasts should be grouped together.

If you open the preferences, and look under "Store", you should be able to select "Automatically check for available downloads" and "Automatically download pre-purchased content".
