Dorico with Synthesizer V

This may be a bit out of place, but I would like to ask those who use synthesizer V with Dorico. I want to use Dorico’s flow to play the intro and the main part of the song separately, but Synthesizer V is not applied to the intro, but only to the main part. In this case, Synthesizer V does not play well, and I am having trouble. When I start Dorico, Synthesizer V also starts, but the playing position is different. It seems to remember that different playing position, and it plays from that position no matter how many times I try. Previously, I started from the intro bar and entered the notes at the melody body position. This worked without any problems. Is it something wrong with the bar information sent by Dorico, or is it wrong to use Synthesizer V like this?
