iPod touch Deleting Songs on ipod, but still shows up on itunes?

i deleted a few songs on my ipod touch itself and when i plug the ipod into itunes it still shows the songs there, but i get the exclamation point. why is this? should i reinstall itunes or something? it doesn't make sense, because then it makes it seem like my ipod has the songs on it, but its not there. and i don't wanna go through each song to see if the exclmation point will show up

You just swipe to the left and delete comes up. On the actual song

I just highlighted all te songs and then deleted ones with the exclamation point. It's not on iPod itself so it's not taking up space. Just annoying cause of my OCD sometimes. Also anyone notices new iTunes doesn't show u album art on left bottom corner when u have it plugged into your ipod
