Do you want to delete that bar entirely, because you only need bars 1-7? If so, see here:
The “Remove Staff” option is for changing the number of staves an instrument has, eg if for a short passage a piano needs 3 staves, instead of the usual two.

Hi All, I did select remove staff which didn’t work. But, forgot to notice that for the trial there are many operations locked.
I’ll be doing the Finale to Dorico Pro 5 special offer. thank you !!
Remove Staff won’t have worked there because there’s only one staff to begin with: an instrument has to have at least one staff!
If you don’t want a bar, you can delete it.
If you don’t want to see empty staves when they’re empty for the whole system, you can hide empty staves (but again, there’ll need to be at least one staff shown, because otherwise there’s simply nothing there)
