Random empty lines around some songs?

[Olelko]

Hi! I've recently switched to MusicBee and I'm trying to configure it to be absolutely perfect, taking Centrol Black skin as a base.
I could do some customisation but I think I see a bug there : https://i.imgur.com/iKNEKvF.png, the lines marked in red only above and below this precise song. It happens with several albums, maybe 5% of total.
What can I do to remove them?

Thanks and see you soon around this forum

Edit : and I've only now seen the "h" in "forgotten", it's now removed.

Welcome to the forum Olelko,

By default MusicBee will separate the discs of an album, so check that all tracks of the album have the same disc number.
Alternatively click the panel header (Album and Tracks) > Customise Panel and check the 'do not separate discs' option.

If that doesn't do it, post a screenshot of the Customise Panel settings.

Thank you! It was indeed the <disk#> tags that were messed up (unexpectedly), everything's good now with some "sorting by" too.
