Control remapping doesn't work

[Hersir]

Hello everybody!

Let me get to the point. I am remaking Umbreon in HD. It's actually very close to completion (I remade all the default sprites, extended animations, made new animations for skills and made new attacks)
It is my first project in fighter factory, so I'm still learning.

I encountered a problem.
You see, I want to use unified control scheme for all my characters, which looks like this:
a: light attack
b: med attack
c: heavy attack
x: character specific special action (in case of Umbreon it's Shadow ball)
y: throw

It went well enough until I tried to remap Dark pulse from Db to Dx (special action button)

It refused. Game doesn't start with an error pointing to CMD string of that new command
It refused to be change to anything but Da, Db or Dc. I tested it further and found out that a lot of other custom skills don't want to be remapped

Can y'all help me figure this out? I will be willing to do small favors like one or two custom animations for someone who can help me figure this out. I'll include the current build here so it would be convenient.

The followings are what you need to modify:

Umbreon.cmd
; (line 454-462)
;----------------
[Command]
name = "D,b"
command = /$D, b
time = 1

[Command]
name = "D,b"
command = D, b

; The followings are newly added commands, you need to add the commands first, then you can use them
[Command]
name = "D,x"
command = /$D, x
time = 1

[Command]
name = "D,x"
command = D, x

; Then find the "Dark Pulse" section
[State Dark Pulse]
Type = ChangeState
Value = 420
TriggerAll = !Var(59)
;TriggerAll = Command = "D,b" ; Comment this statement, i.e., add ";" before this statement
TriggerAll = Command = "D,x" ; newly added TriggerAll
TriggerAll = StateType != A
