My guess is the way things are getting cached now:

I have logo1 and I never entered episode level...
Then I changed logo1 to logo2 and when I enter season or episode level for the first time the new logo shows on episode level while the old one shows on TV level...

Same thing just happen for me, I never ventured into episode level on "South Park". I've since changed my logo and now I have the new logo on episode level because it's the first time being cached....

Unfortunately only way to resolve the issue is too delete the thumbnail files inside userdata folder.

**EDIT**
Actually it's view based, if you never used a view then changed a logo it will show the new logo on the view you never used before and show the old one on views you have used and has had the images cached on...
