I had this a few years ago. A reanalyse sorted it as for some reason (not even sure how or why) the waveform was from a different track! I also had it with the small overviews too.
It could have been a faulty Serato DJ library import that did it. Either way, reanalysing sorted it for me. That’s not to say it will fix it for you though but worth a shot. Also cleanup on the library to be sure.
It’s ‘ye olde’ now but think this was it: Brandnew Prime 4, Waveform displayed incorrectly
