problem with note spacing

I noticed a problem with the spacing of the attached file.
Is there a way to get the spacing in the full score back to normal?

Fantazia 2_probably (1.4 MB)

  1. I closed and reopened Dorico, this did not help.

  2. I exported to music.xml and reimported into Dorico: now it is fine again.
    Still, what had happened?

The file is not corrupt: choose View > Signposts > System Breaks so that you can see the signposts for your breaks, select the first system break (on the third system of the first page) and toggle the ‘Wait for next system break’ property on and off again. That should sort it out.

Oh, thank you Daniel, I must have played with the visibility of the signposts…
Have sorted it now, everything is fine.
