iPod touch Album Art thumbnails not working

[Fatigue]

i recently decided that i should delete all my music in my ipod and put the only albums that i like, so i did that and added the choosen ones than i noticed that there was no album art thumbnail on every single album.
i still cant get the album art working in 2 albums in my ipod, everything seems fine on itunes, meanwhile my ipod is a mess
i tried deleting, then syncing again, adding it directly into the ipod (right click, "add info" or something like that, since my itunes is on spanish, and finaly filling tha album art field)
i can only get the album art o be seen via coverflow and now playing, but in the thumbnails you can notice that when i flip the album art the small preview doesn't has album art too
i'm not interested on updating or restoring thanks

there you have the pics of my problem

You're not the only one.
I have the same problem, but only with albums that are converted (in my case, from ALAC to AAC 256kbps).
