Hello,

This happens whatever the style I try to load.

In my case, the first 12 Bars are in a Bluegrass style: _BGBDBS8 Fast Bluegrass Eights 260 Banjo Solo, I reduced the Tempo from 260 to 230.
At Bar 13, I made a style change for the rest of the song: _BLUGRF8 Classic Bluegrass 8ths 260 Fif. I also reduced the tempo to 230.

Again, the name of the style effectively changes at Bar 13 but I keep the same sound.

All the tracks are unfrozen, I checked it.

About "What add-ons ...", I am sorry but I don't know what to look at. This is confusing.

Best regards
