I’ve had a couple of situations like this in which Dorico allowed too much space to certain lyrics to the detriment of the rest of the bar. I’ll try to post an example when I get home and can run Dorico. Looking at your example, you might reduce the amount of ‘padding’ for hyphens in your settings.
To be fair, you can only get results like your Lyric clashes example in Finale if, for some reason, you’ve turned off Automatic Update Layout and haven’t thought to update manually.
To be fair #2: barring your second layout example which might be possible to accomplish by changing some settings, how is any software program supposed to be able to produce good layout if you force its hand in advance?
