Podcasts grayed out when syncing older iPod
When I synced my iPod Classic with iTunes, I didn't have enough free space for my podcasts. I deleted music I didn't need to free up space, but now my podcasts are grayed out on iTunes when my iPod is plugged into my computer and have been deleted from my iPod. How may I restore them to the iPod? Many thanks!
iPod 5th Generation (Late 2006), OS X Mavericks (10.9.5)
