Would you please post the song? You can’t do that here, but you can create a public place on Dropbox for free, upload the song, and post a link here.

You hinted at time base but skipped answering the first part of my question. Are you using any RealTracks with a half or double-time time base?

I uploaded the song (actually a backing track) "Old Dreams" on DropBox.
Here is the link: https://www.dropbox.com/scl/fi/w17llqqt9xx491014ocn6/Old-Dreams-0-Short.SGU?rlkey=c8un1ez1rzj1enzljrdr5rt5t&dl=0

If you find another way to program a change of style at the right position, I would be very glad.

To answer your question, I am only using Styles with half-time base.
These are: BLUGRG8 Bluegrass Reso Solo 8ths at 260
