In Song Settings > Avoid Transpositions if that is unchecked you should at least be getting an F7 or A7 transposed as well as a G7.
You can load the style and freeze all the styles tracks and generate a whole Utility track of G7 with the instrument you need and see what you get then you can freeze that track, paste the song chords, unfreeze the style tracks, generate then in then in the Audio Edit window with snap enabled copy the good sections from the Utility track to the style track that has been generated and replace the bad sections with the good sections.
