I FIGURED IT OUT!!!
I kept searching through posts and, eureka!
First, import only the first song in the group. Then select the song and select edit the song. In the subsequent screen, on the left, is the title of the song and to the right is a plus sign. I clicked on the plus sign and added another local file. I continued the process until I added the remaining songs.
whew! ( but, this was not the way I accidentally did it before! )
