Synchronization

Each custom layout is saved as a variation of the default layout. This means that only those attributes that are different from the default layout are stored with the custom layout. Unchanged attributes in the custom layout are in synchronization with the default layout. When you make a change in the default layout, that change will be reflected in an existing custom layout if, and only if, the affected attributes are in sync (the same as) with their default layout counterparts.
