Will show groups 1, 2, 3, 4, and 5 only, regardless of how many people are in your raid.
That's what I have selected, however when anyone is moved in the raid or someone leaves/joins, it defaults back to By Group 40
Edit: I cleared out all my Grid settings and installed from scratch. It seems to be working fine now.
