Don't see all instruments

still a newbie, have this is my first score with many players, and I don’t see them all listed in the full score. ?
It’s a conventional big band, see attached photo. The trumpets and trombones are there but not the bass trombone or any of the 5 saxes.

Can you attach the project?

I came back from a break and didn’t have the same problem. I must have been in some kind of global mode rather than the flow
will delete this query

Well, it’s also possible to have more than one “full score”, so perhaps you were looking at the wrong version that has had instruments removed. Your list of layouts is quite long, and it looks like there are another 7 or 8 that are off screen.
