I am having this exact same problem with my iPhone Pandora App. No thumbs show up anywhere on a desk top web browser. When I go to my iPhone Pandora App, I have "ghost" thumbs. I have deleted all my thumbs from my current station collection (1 at a time), and when I go to my profile it says 0 thumbs. However, under my profile, but when I press the 0 (thumbs) it displays a list of thumbs. I am guessing they are orphaned thumbs from stations that I have deleted. I was able to remember one of the stations and re-collect it, so I could delete the thumb. I have no idea where the other thumbs may have come from. Anyway, if you could clear all my thumbs lists entirely, that would be great. I just upgraded to premium, and I just want to start fresh with a clean thumbs list. Thanks!
