Why is Path variable behaving like other user variables in "Edit environment variables for your account"?

I tried to add a path to the Path variable using chatgpt prompts (which I should not have done)

setx Path "%JAVA_HOME%\bin;%PATH%"

Now I can't see the old path variables nor add new path variables. The system functions fine until now but I don't know what I should do to revert back the behaviour.
