tl;dr: If you’re exporting MusicXML from Dorico and it’s a mess, try removing all your chord symbols and then re-exporting - it might help!
I’m aware that exporting MusicXML from Dorico is not something the developers have had a proper chance to work on, yet, and that there are a few old-ish posts on this forum regarding the shortfalls in the current implementation. I think I’ve just discovered something that hasn’t been mentioned thus far.
Basically, when exporting MusicXML from Dorico a hidden rest is added to every place where there should be a chord symbol. I think the rest is the value of whatever the previous note was, but haven’t tested extensively enough to know definitively. If I remove all the chord symbols everything (in this simple file) transfers pretty much exactly how I’d hope it to.
I have in front of me Dorico 1.1, Sibelius 8.5.0 (my free upgrades have run out), and Finale 2011 (which I only use for opening ancient files).
I’ve attached the zipped-up Dorico project but, to be honest, it’s nothing special - it’s a native Dorico 1.1 file with everything pretty much default.
Here’s what I put into Dorico - it’s intentionally really really simple:
Here’s how Sibelius renders it. Note I’ve not touched spacing, and view Hidden Objects is actually turned on. I can’t see any way of making these bars rhythmically correct, but trust me, they don’t play like 4/4 bars!
Finale usefully shows me what Dorico’s actually done (ignore the fact there are no accidentals; that’s already been explained elsewhere and the solution is to run Canonic Utilities in Finale and clear frozen accidentals):
Could fixing this maybe be added to the to-do list, please?
