How to color balance only selective layers?

[Advent]

You have to group the 10 layers on top.

To do this create a new group: Layer>Group Layers; Ctrl+G (Or in the bottom right of the layers panel next to new adjustment layer and layer effects)
Then drag your 10 or whatever layers into that group.
Set the Group's Blending option to Normal, (not the individual layers, the actual group)
Then create your adjustments inside the group as well and they will only apply to the layers in that group.

I tried this and it does not work. I'll edit in some pictures.
