Some delays not showing in track viewer

[Wrymouth]

Mamar appears to hide some delay instructions despite them being present in the song.
The first image below is the track as viewed in the newest version of Mamar. The image below it is the track as seen in the .ron file exported by an older version of Mamar.

When I preview the track in the newest version of Mamar, what I hear lines up with the .ron export and not with the view the app displays.
