I just got a version 2.0.0 upgrade from the FS2020 Marketplace. It seems to have fixed the trim function so that it is now independent of elevator (ie, not autotrim). However, its sense seems to be the opposite of that of every other aircraft, so I've had to make a separate control profile for it. Thanks to @mmcwill1 and @Luis Hernandez for their suggestions. I feel that Luis was on the money.

I can't get the elevator trim of the CS717 to behave in FS2020. The aircraft initially reacts to trim changes, then seems to compensate for the trim setting and reverts to its previous climb/descent. It's as though it's on autopilot but I really don't think it is (because I never engaged autopilot and it looks to be off). I've seen one other report of this issue, but I gather it works properly for most owners. Does anyone else here have this problem, or know what I might be doing wrongly?
