Unbinding keys on Graal client

[shrimps]

Does anybody know how to make Graal unbind keys in F3>Keys option?
I can change them and everything but it doesn't save unbinds.
I've edited the game_config file, set as read only, none of this changes to save unbinds, it changes the game_config back to default. Read only doesn't change but the client still shows it bound anyway.

I want it to look like this every time I log on but it doesn't ever save.
Instead I get all the IJKL and number pad keys all back on there when I re-open Graal.

PS. I've always had this problem even back on V2 no matter what computer or Windows operating systems I've used.
