Why do I see all project schemes on my new field configuration scheme?

[Kevin Dickson]

Hi all,

I've created a new field configuration screen that I only want to use for specific projects.
However, ALL screens for every single project are appearing in the new scheme.
If I delete them from my new scheme, they get deleted for the default field scheme too.

How can I ensure that only my newly created screens show up in my new field configuration scheme, without affecting other projects?
