When i use window.devToolsExtension() there is a Warning: Failed prop type: Required prop monitorState.position was not specified in DockMonitor.

Most likely, you're having both vanilla Redux DevTools and our extension. You should include only the extension, which is just one line of code, without any monitors needed (especially DockMonitor).
