Lyrics doesn't sync with my 5th Gen iPod Touch

12.2.2.25 Itunes Win 8.1

Its been like this for a couple of weeks and I can't seem to solve it.
It only happens to songs with no lyrics attached to them and I want to replace them because the lyrics are wrong or to change a spelling error.

Songs with an empty lyrics box and putting the lyrics in myself are fine. It syncs well.

I tried deleting and syncing then adding them back and syncing but it doesn't work.

Please help, thank you.
