The Effect/Composition Stack widget always refers to the timeline clip that is currently selected. Each effect can be temporarily disabled by clicking the eye icon, or all effects for that clip can be disabled using the check box at the top of the Effect/Composition Stack widget (the settings are saved though), this is e.g. useful for effects that require a lot of computing power, so they can be disabled when editing and enabled again for rendering.
