Happy to help. That’s not at all the behavior that Card Designer users are experiencing, so let’s figure out why. If there is a bug, I’ll fix it. I know there are others who use the project settings and Card Designer settings together without issue.
First let’s make sure both Blocs app and Card Designer are latest version. Blocs had reports of issues with custom brics in some prior version so it’s always best to stay up to date with both.
How Project Settings works with Card Designer
If you take a fresh blank page/project and add Card Designer without touching any settings, you should be able to add project global settings and they will effect Card Designer because you have not made custom changes. But once you make a custom change, it should stick regardless of Global settings.
