A developer is using UiExplorer to modify selectors.

Explanation

Repair enables you to re-indicate the same target UI element and repair the selector. This operation does not completely replace the previous selector. The button is available only when the selector is invalid.

To indicate a totally different selector and replace the previous one use Indicate Element.
