Artist Thumbnail some of them show some don't

I'm having some problems in my music Libary Artist view

I have used correct mp3-tags on my mp3's and put them in a folder on my nas. (every album has it's own folder)

In every folder I have a folder.jpg.

I use libary view and have installed the Universal Artist Scraper.
If I browse the albums, every cover show as it should. But when I choose Artist, some of the artist get a correct thumbnail but lots of them are emty thumbs. I have repeatedly updated the libary and clicked "Query info for all artists" but the thumbnails refuse to show.

If I right click an emty artist thumb and choose 'Artist Info' I can click "Get Thumb" Than I can choose a couple of Remote Thumbs of the Artist.

So the thumbs are being downloaded and are there but refuse to show up.

I can manualy go to the '' Artist Info' of every emty thumb and than click the 'Get Thumb' button but that will take forever.

Can someone help me with this?
