How to visualize preset styles

I’m sorry to bother you again but I’m very close to the “rabbit hole” in setting all my workflow with scrivomatic.
I successfully imported compile presets in scrivener and I can see them in compile/edit format/styles.
The problem is that while in the sample scrivener project downloaded from
I can see the styles

, in my project (I imported preset styles in my formats and also in project formats), I can’t see nothing in styles drop-down menu.
What I missed?

Thank you
