Control setup

[Wind Ark]

I cannot explain how angry I am with how awful the current control setup is. I am on keyboard, and I have finally figured out how to set my movement to WASD, ok that's good. Now I have found my way to the key input, and it lists like 4+ buttons for the same key, and I can only assign more. How do I remove some of these ♥♥♥♥♥♥ keybinds? Anyone help please, this system is breaking my head, how did it get this convoluted.

Desired setup:
-Movement: WASD
-Weak Attack: J
-Strong Attack: U
-Jump: K
-Special: L
-defend: i/o
-"clutch": i/o
Probably something along these lines. Based on how I used to play Act Cadenza Strife way back in the days. There's probably more to say but until I can play the game without awful controls at least I can't exactly say more. Thanks for anyone willing to help, I am frustrated here.

Found this to help, it did work but man is it a workaround. If anyone important reads this, get on making a normal keybinding system, this was aids.

On a side note, tried playing a match but was awful. Kept trying to press my up key to jump as an option but it didn't work. I still have to test the "tap jump" options and stuff to see if that fixes it, but having my W key bound to jump and the directional up did not work for both. :/
