I have moved your post to Working in Archicad and have deleted the poll as this in not a wish.
You are on the right track.
The option is in your Work Environment.
When you change the settings you should store that scheme (for that section) as a new scheme or redefine an existing scheme.
Then in the actual Work Environment Profile you need to create a new profile or amend and existing one to use your scheme that you just adjusted.
Now set that profile as default so it is used next time you start Archicad.
Don't forget to apply the settings so they become active straight away.
