Yup. You made a Blueprint without any script (nodes) inside of it. This is referred to as a Data-Only BP. They’re great for holding important data you want to access later.
The other thing you did was (at some point) close the Class Defaults window that comes up automatically. What is supposed to happen when you open a Data-Only BP is that you’ll see that window pop up. But if you ever closed that panel, Unreal is trying to remember your preferences and keep you from having to close it in the future.
Now that you’ve reopened it, you should be okay moving forward.
