PC platform running windows 10 Home.

I purchased a finale score from Praise Charts online store. I am having 2 issues with this score.

First, a lead line is shown on the score, but when I got to print that as a Lead Sheet, it also prints a hidden line that is an SAT part. I don't want the SAT part to print, but I cannot see it in the score to delete it.

Second, I have deleted all the lines from the score that I do not need to print. This leaves the Lead Sheet line and the Piano line. I would like to print those together on one page for my piano player. When I print, it will print those items but it prints them in a very reduced size, like I would expect to be a score. However, this is too small for my piano player to use. How do I get that set to print together at normal size?

Thanks for your help!
