a system collision on a specific page without a reasonable reason

Dear users and developers.

There is a system collision on the right page in the following picture:

As far as I understand, Dorico should move the second system on the right page onto the next page.

I cannot find what I did wrong.

Could anyone look at the zipped dorico project file?

Thank you in advance!

This has been discussed and explained in the past, see here for example. Dorico probably wasn’t expecting the double lines of lyrics when deciding to put two systems on the page, because that decision is made first and is based on different assumptions. You did nothing wrong, just have to add a manual page break.

Thank you for your kind explanation!
