same code, differnt result (hex code)

[Denloself]

i am trying to make hex code being uncoloured (i know the correct format in skript should be <##hexcode>) and then i found out it was not working, when i am trying to debug it, i found out i used two exact same code and and differnt result

i used essentialsx and essentialsx chat, i am not sure is it because of them.
and also, i tried same code on my test server

result of same code on my test server (also installed essentialsx):

result of same file on my test server (still installed essentialsx):

code i used:

command /rainbowxd2 <text>:
    trigger:
        message "&7&m                             "
        message "&7/rainbowxd2"
        set {_name} to arg-1
        message "%{_name}%"
        message uncoloured "%{_name}%"
        message length of uncoloured "%{_name}%"
        if length of uncoloured "%{_name}%" <= 4:
            message "pass"
        else:
            message "fail"
        replace all "§" with "ｃｏｌｏｒｃｏｄｅ．" in {_name}
        message "%{_name}%"
        message "&7&m                             "

command /why <text>:
    trigger:
        message "&7&m                             "
        message "&7/why"
        set {_name} to arg-1
        message "%{_name}%"
        message uncoloured "%{_name}%"
        message length of uncoloured "%{_name}%"
        if length of uncoloured "%{_name}%" <= 4:
            message "pass"
        else:
            message "fail"
        replace all "§" with "ｃｏｌｏｒｃｏｄｅ．" in {_name}
        message "%{_name}%"
        message "&7&m                             "

and... if anyone know how to uncolour hex code with that format, please tell me
