The left set of keys were changed fine down to the last one.
Activate Perk 5 actually updates "Change Stance".
The right column of keys appears to be offset by 1. When I try to change "Camera Forward" it updates "Activate Perk 5".
"Camera Back" updates "Camera Forward" and so on. Clicking one in the right column changes the entry above it.
I don't know how to change the last setting as "Toggle Mouse Scrolling" changes "Focus Next Unit +5".
This looks like the same kind of problem you had once before.
