00:40:533 (40533|2,40690|2)-The melody of these two notes is clearly different from the melody sound of the jack used in 00:40:377 -, so I think it is reasonable to use it in another col.

00:55:957 (55957|1,56113|1,56269|1,56425|1,56582|1) - I think there are a bit too many anchors here, maybe you can move 00:56:425 (56425|1,56582|1) - these to col 1 instead to make it slightly more comfortable
instead i changed the pattern in Another diff
