Library Concepts

In Twin Builder, library component definitions are intended to be accessed once per component, when you place the first instance of a component onto a schematic. Once a component is placed, the definition for the component transfers from the library to the project file.

Editing a component definition and updating instances is then controlled from the project definition, which is listed in the Components folder in the Project tree.

In other words, you do not edit component definitions in the library, but in the project. If you want your edits to be reflected in the library definition, for use in another design, you must export the edited components to the library.
