Can't Rebind Cancel Ability Button

[JustEggSalad]

Despite changing the "Change Cancel Ability Mode" to "Cancel Key" and setting a different keybind, only the UI responds to this change.
The cancel prompt correctly says my bind instead of "C," but the new bind doesn't work and the game still responds to "C" anyways.

Only experienced this on Kelvin, may apply to other characters.

I am having somewhat the same experience on Ivy. My global cancel key for abilities is E, which works for most heroes, but specifically on Ivy's Sky Drop ability it does not work.
