Mysterious blank "-0:00" tracks in album view

So, in the endeavor to rectify iTunes idiotic album rating system, I'd been going through said albums and found...a very strange bug. Basically, several albums contain these "songs" with no name, "-0:00" duration, and a complete inability to interact with them"

There's no rhyme or reason to these glitchy tracks, either - doesn't matter if the album has one song or ten, if I burned it from a CD or downloaded a YouTube rip...and the number of blank tracks varies wildly. But again, I can't interact with them - I can't rate them, right-clicking only brings up "paste," and nothing appears when clicking the ellipses to the right of each track.

They're not really harming anything, nor do they show up in song or artist view (just in album view), it's just...weird. And kind of annoying. Anybody have any idea why this is happening and/or how to fix it?
