Hello Mavros!
As mducharme has already pointed out, the expression map in your screenshot must have been modified. The Synchron Strings Pro expression maps that come with our Dorico Wizard have CC1 assigned as secondary dynamic. Please note that expression maps gets saved with your project. So if you load a project, the expression maps inside will stay as they have been before a fresh installation.
I'm not sure which instrument you are showing in your second screenshot, but it's true that Synchron Woodwinds, SYNCHRON-ized Woodwinds and Synchron Brass work with CC2 as secondary dynamic and Synchron Percussion works with CC1 as secondary dynamic. That's no mistake. The auto-assigned presets are in line with this setting of the expression maps.
Best regards,
