Finale 26, iMac 27" 2015 build, Mojave

I'm working on a Bach orchestra arrangement with a lot of trills. I've got Human Playback set to Baroque so the trills will start on the upper note. The piece is in C Minor. In one measure there is a C on the first beat which needs a trill. I'm using the Articulation trill. The trill needs to go between C and D Natural, but Finale insists on playing it back as C to D-flat, I think because there is a D-flat later in the same measure. The only way I could find to get it to playback correctly was to put a grace note D before the trill, but this changes the timing of the trill. Is there another way to deal with this?

Thanks!
