Component Behavior Problem

I’m trying to model a chessboard by creating two separate components for the black and white squares. However, when I attempt to individually push/pull any square, the changes only apply to that specific square. Normally, when you edit a component, it creates an isolated box for edits, but in this case, it acts like a regular plane. The rest of the squares stay the same. Oddly, when I bring them from the component tray, they behave as components without any issues. What might be the mistake in my approach?"

When you first created the component, you had the “Replace selection with component” unchecked so what you are push-pulling is the original face that remains unrelated to the component definitions.

Yes, thankyou for quick response
