[bug] Discrepancy between generated staff layer and staves in Neon (Neon looks worse than it should be)

Some examples:

If I look at the generated staff layer for NZ-Wt Msr3 013r, the staves are absolutely perfect:

But when I go to Neon, the last staff is super tiny:

In the case of CH-Fco Ms2 006r, the staves it found are bonkers:

And I can't figure out if those staves match the Neon staves... at first glance, it looks about right:

But looking at the first staff, I experience confusion. In the generated layer, it looks like Paco+Kyrie's magic found two lines (as indicated by the pale blue boxes around the top and bottom line):

But in Neon, that line has two staves:

Is that normal?

These are the two images I used:
