staves distance

I tried the above advice but can't get it to do what I want. I have a simple vocal score with lots of space between its two staves. I followed the above advice: 1) open Breaks and Spacer, 2) cilck and hold on the rightmost Staff Spacer (looks like an I), 3) drag it to the first measure of the top stave, and let go the mouse. There is now a capital I type icon but not in the first measure; it moved itself over to be below the clef sign at the beginning of the stave. 4) double click on the I thingie and a blue box appears beneath it. Now by moving the spacer, I find I can increase the distance between the staves still more than it already is. But that is exactly the opposite of what I want. That space is too big to begin with, and I want to reduce it.

Is there any way to do this? Note that I'm not talking about simultaneous staves, that is, the treble and bass staves of a piano part that are played together. I'm talking about a single vocal part that runs on to multiple staves.

After writing the above, it occurs to me what the problem might be. That empty space between the two staves is there because it used to be filled with lyrics I deleted because I want to reformat the whole score, putting most of the lyrics together in a box below the melody. It looks like what I have to do is just create the score again from scratch. Ideally, one should be able to select a whole stave and move it around, just like words. That would be the dream solution.
