As far as I know you need to use 'Ctrl-a n' to move the screen focus into the next region of the split screen and then 'Ctrl-a c' to start a window in this split region with a shell in it. Otherwise it remains empty. You could also use 'Ctrl-a 0' to display the content of the first region of the screen in the second split region - mirroring what the first region shows. 'Ctrl-a tab' switches focus between regions. 'Ctrl-a n' switches the displayed window within a region to the next window which has an active shell in it, within the screen session. Instead of 'n' for next, or 'p' for previous, you can enter the number of the window, with 0 being the first window in the screen session. I'm not sure if I explained it an understandable way, but I think with a bit of experimentation you'll soon understand how screen sessions, windows with shells and split regions work.
