How to reproduce?

vendors~main.manager.bundle.js:84538 Warning: Encountered two children with the same key, `pages-wallet-start-up--start-up`. 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.
