condensing slurs etc.

I think that in general a complete guide for condensing and condensing change is needed.
In particular I have a problem in condensing slurs, as you can see in the attached project.
In the clarinets stave the slurs are both correctly shown, while in the horns stave they don’t.
I’ve tried fiddling with condensing changes, but I have not enough information.
Any help will be very much appreciated.
Thank you in advance

slurs (557 KB)

When the horns are notated in a single voice (as they are in e.g. bar 2), then Dorico will only show a single slur. It’s not necessary to show two slurs under such circumstances, indeed I would go so far as to say it should be discouraged, and Dorico does not provide an option to do this when condensing. Perhaps you would prefer Dorico to consistently use two voices throughout if you want it to show slurs on both sides throughout?

Thank you for your kind answer.
Unfortunately I’m working on a score that is written that way and the publishing company would like to preserve the same writing.
However a comprehensive guide to condensing options and behavior would be a blessing.
I’ll see what I can do.
All the best
