IPod is not showing correct information

Question

I recently updated both my iTunes and my iPod. Now I have iTunes 12.0.1 and I have iOS 8.1.2 When I sync my music, either manually or automatically, the information appearing on my iPod is wrong. If I sync an artist that has 5 albums with songs reaching into the 100's, the iPod will read that it has 1 album with 4 songs. I even watched iTunes go through and copy the songs onto it but it doesn't show properly.
Sometimes, I will uncheck and check the artists then sync, and the album covers are missing. It happens to some of my artists and I even went through the process of backing it up from an older backup and it still won't work. One album has three songs but when I search the iPod for the missing ones, they're there but aren't showing up in the album. It just bothers me when half of the cover images are gone and it doesn't say the correct information nor show all of my songs.
