Also there is a bug in Dorico regarding the divisis

This is documented in the Manual.
Excerpt:

And is already well on the radar of the Team:

Missing divisi staff

Yes, it is the case that Dorico will only respect the first divisi transition on a given system, and this is clearly documented: We do hope in the future to add an option to allow staves to appear/disappear mid-system, which would make it more feasible to allow the number of staves to change anywhere.
