Dorico takes one approach for each phrase, where a phrase is defined as the stuff between rests. The answer to your question about clarinets vs bassoons is probably off the left edge of your screenshot; in order to answer the question definitively we’d need to see everything between rests, not just this one system.
You can force Dorico to start a new phrase (and thus take a new condensing approach) by adding a Condensing Change from the Engrave menu. Even if you do nothing more than tick the relevant players in the left side of the dialog, this will force a new phrase.
More generally, the options in the right side of the condensing change dialog act as a local override for what’s in Notation Options > Condensing. These options (in both places) are extremely specific; expect to spend a little time experimenting in order to figure out how each option interacts with your music.
For your flutes, I have no idea what’s supposed to happen if a player appears to be playing two instruments simultaneously, such as in the fourth bar of your screenshot - or have I misunderstood? Dorico’s generally capable of condensing the first instrument held by each player, but there’s a limitation there, so if you have a Flute 1 that only plays flute, and a Flute 2 that also holds Picc, you probably want the Flute 2 player to have Flute at the top and Picc underneath, in the left panel of Setup mode. That way the two flutes will condense where possible, subject to your settings. (And quite often when pairs of instruments won’t condense at all it’s down the pitch crossing settings: by default Dorico doesn’t like instrument 1’s pitches to be below instrument 2’s pitches for more than one or two notes.)
Bar 17 bassoons: have you inadvertently given both pitches to both bassoons, perhaps? That might explain the weird double-chord.
