@droidgoo relationship between master page and components can sometimes get tricky. But the behavior you’re describing is correct.
The basic principle of master pages is that they have two parts:
- Fixed, un-editable parts
- Editable parts
Fixed parts will be the same on the master page and on all its child pages. It doesn’t really matter what you put in them. In your case you have a component with editable areas. But because the master page section itself is not editable, whatever is in the component on the master page will be displayed on child pages as well.
To have different versions of the component on master and child pages, the area of the master page where the component is placed must be editable.
I prepared a quick example project that shows these 2 situations:
