Last system won't go to right side margin

In the attached screenshot, I am in engrave mode, the last system will not go to the right side margin. This is where I want the system break. How to make it do that? It is going to the printer in the morning, would appreciate making this last system look right. Thank you!

Go to Layout Options → Note Spacing → Only justify final system in flow. Set some smaller value - 50% ought to do it.

Alternatively, switch the checkbox for that option off altogether.

Thank you Daniel for your quick reply…I’m going to meet my deadline with a beautiful looking score!
