Have you tried forcing a texture cache update? Download the script, and run "./texturecache.py C sets" - if you still have a problem after that, your artwork sources are wrong (view them with "./texturecache.py jd sets").
Texture Cache Maintenance Utility: Preload your texture cache for optimal UI performance. Remotely manage media libraries. Purge unused artwork to free up space. Find missing media. Configurable QA check to highlight metadata issues. Aid in diagnosis of library and cache related problems.
