# Issue The cache updates are performed in a wrong way, resulting in a duplicate collection: **Error:** ```log webpack-internal:///./node_modules/react-dom/cjs/react-dom.development.js:88 Warning: Encountered two children with the same key, `6f3f7265-0d97-4708-a3ea-7dee76dc0a0a`. Keys should be unique so that components maintain their identity across updates. Non-unique keys may cause children to be duplicated and/or omitted — the behavior is unsupported and could change in a future version. ``` **Video:**  # Fix **Video:**  |
