Copy Chord Change Symbols from one file to another?

I have two files open of the same duration.

One has chord changes the other does not.

Everything else is the same. I can select just the chord changes from one file and copy them.

When I try to paste them into the other file they do not appear. Is this possible? What might I be doing wrong? Thanks.

Well duh. I was trying to do it in Galley View. It works fine in Page View. Nevermind.
